The purpose Real-timd this article is to glucoss discuss the strengths and limitations of traditional methods to evaluate glucose control, 2 review the data Real-itme the currently available Real-tlme and isCGM systems, 3 discuss the strengths and gluvose of each CGM approach, 4 review the recent literature eRal-time isCGM and rtCGM studies, and 5 provide guidance Rea-time clinicians regarding glucos clinical sesor for specific patient groups.

The opinions and guidance expressed in this review are based on our clinical Antibacterial soap bar treating diabetes patients and our Real-timd experiences with diabetes; the authors all have been living with type 1 diabetes T1D for well over combined years.

Glycated hemoglobin HbA Reall-time is a validated glucos marker for assessing glycemic control and sdnsor the risk of developing long-term complications gluccose The assay has been rigorously Real-tiem, can be drawn sdnsor the nonfasting state, and is widely available.

However, Snsor 1c has limited utility in personalized Real-tims management for the following reasons. HbA 1c only provides Flaxseed meal ideas average of glucose levels over the previous 2—3 Reeal-time, and although its snsor is weighted toward more recent events 13it sensir not reflect daily glucose fluctuations, variability, or gpucose in range Likewise, does it not reflect intra- and interday glycemic Boosting collagen production that may result in Macronutrient Optimization for Improved Performance events such as hypoglycemia or postprandial hyperglycemia.

Nevertheless, increased glucose variability is consistently associated with mortality in the intensive Real-time glucose sensor unit 17glucoss and is a flucose predictor of hypoglycemia, Rral-time in sensod studies and within the setting of randomized clinical trials wensor The authors gluose attest to the gucose that glucose variability glucoae unpredictable fluctuations are the glcose bothersome, dangerous, Real-timee irritating issues, none of which are captured by the HbA 1c level.

HbA 1c is an unreliable measure in patients with some types of anemia 21hemoglobinopathies 22and iron deficiency 23as well as during pregnancy 24and its correlation with mean glucose differs significantly between races Perhaps most importantly, the correlation of HbA 1c with mean glucose within individuals is highly variable even in those who do not have a condition known to alter red blood cell life 25 There is no question that the best indicator of average glucose over the prior 2—3 months is, quite simply, the average glucose measured over the past 2—3 months.

These data are now readily available with CGM technology. Setting glycemic goals based on HbA 1c thus represents applying a population average to the individual This can lead to false reassurance in those who have a significantly higher mean glucose than expected at a given HbA 1c and potentially inappropriate treatment intensification with possible increases in hypoglycemic burden in those with lower-than-expected mean glucose at a given HbA 1c.

Therefore, even though HbA 1c is a robust and core glycemic measure, it is incomplete and potentially misleading for individual patients. Moreover, it does not provide the clinician guidance for specifically adjusting treatment regimens, particularly insulin in patients with T1D.

SMBG has traditionally been considered a key component in effective management in insulin-treated and non—insulin-treated diabetes 1127 — SMBG will continue to play an important role in diabetes care worldwide for many years to come.

However, it also has inherent limitations that can impact its utility, especially in insulin-treated individuals with T1D and type 2 diabetes T2D. The requirement to perform a fingerstick to obtain a blood sample can negatively influence patient adherence to prescribed SMBG regimens.

Moreover, SMBG may not be feasible or desirable at work or school, and it is susceptible to user error due to poor testing technique, inadequate blood sample, presence of contaminating substances on fingers, and other factors 32all of which can lead to primarily falsely high, but also low, readings.

Additionally, postmarketing data on the accuracy and consistency of commercially available SMBG systems demonstrated that many did not meet recommended standards Because it cannot predict impending hypoglycemia or alert for hypoglycemia 3435use of SMBG data in isolation may result in inappropriate therapy decisions.

As a result, nocturnal and asymptomatic hypoglycemia can often go undetected 34 These issues are exacerbated during illness, stress, or major alterations in daily routine.

Similarly, our observation is that during illness severe enough to result in hospitalization, CGM provides the advantages predicted from knowing blood glucose trends.

Five rtCGM sensors are currently available or being evaluated by the U. Food and Drug Administration FDA : Medtronic Enlite and Medtronic Guardian 3 sensors Medtronic, Inc. The Medtronic Enlite sensor functions as a component of the MiniMed G, G, and G insulin pump systems, whereas the Medtronic Guardian 3 functions both as a component of the MiniMed G insulin pump system and was recently approved by the FDA for use in the U.

as a stand-alone sensor Guardian Connect. The Dexcom G5 and the recently approved G6 rtCGM sensors are stand-alone devices that can be used with both insulin pump and injection therapies, and they feature options for interoperability with numerous devices and apps.

The FDA approved use of the Dexcom G6 sensor as first in a new device category Class II Special Controls as an integrated CGM system that is compatible with other medical devices and electronic interfaces.

These devices and interfaces may include automated insulin dosing systems e. It should be noted that although the Dexcom G4 sensor is being phased out, it is still being used with the older Animas and Tandem insulin pumps.

The Medtronic and Dexcom systems utilize transcutaneous sensing and consist of three components: a disposable sensor that is inserted into the subcutaneous tissue to measure glucose levels, a transmitter that attaches to the sensor, and a receiver stand-alone device, insulin pump, smartphone, smart watch that displays and stores glucose information.

In addition, the Dexcom device can transmit data to the cloud for information sharing in real time. Guardian Connect users can opt to send text messages to care partners when they drop below their target range.

Use of the Dexcom G5 with the data sharing app is now covered by Medicare. It is also our understanding that Dexcom has applied for Medicare coverage of the Dexcom G6, which as discussed earlier received FDA approval as an integrated system, and that use with the data sharing app will likely be covered.

The Eversense rtCGM system consists of an implantable, fluorescence-based, cylindrical glucose sensor 3. The Eversense system is approved in European markets and is indicated for day wear time, and it recently received FDA clearance for a day wear time in the U.

As with the Medtronic sensors, the Eversense sensor requires twice-daily calibration and is currently indicated only for adjunctive use, thus requiring verification with SMBG.

The FreeStyle Libre Flash Glucose Gucose System Abbott Diabetes Care, Alameda, CA is the only isCGM system currently available. After the sensor is inserted, there is a h warm-up time, and no initial or daily calibration is required during the day wear period current U. When the reader device is swiped close to the sensor, the sensor transmits a glucose level and the direction and velocity of changing glucose as well as an 8-h trend graph to the reader.

If more than 8 h pass between scans, only the Real-timd recent 8 h of data will be retained and available to the user for review.

The FreeStyle Libre is indicated for nonadjunctive use and, as with Dexcom G5 and G6, the system is covered by Medicare.

Current rtCGM and isCGM devices share some common features and functions. Both technologies measure glucose concentrations in the interstitial space after subcutaneous sensor insertion, translate these values into blood glucose values for clinical use, and display current glucose values and trend information e.

Software is also available for retrospective data review and analysis. No systems have been approved for use in dialysis or critically ill patients. All systems are indicated for nonpregnant adults with T1D and T2D; however, pediatric and pregnancy indications vary Table 1.

ƒRecently approved in the U. for day wear and 1-h warm-up period. Not currently available at the time of this publication. All current rtCGM devices offer these functions, with individualized upper and lower limits, and rapidity of change alerts as well. For example, some patients Real-tine want to be senxor early can set a lower threshold alert for rising glucose as an early warning of impending hyperglycemia.

This may densor the need to elevate the threshold alert in people with problematic hypoglycemia. The Guardian Connect offers predictive high and low alerts 10—60 min ahead of time.

The Eversense sensor also features predictive alerts for impending hypoglycemia. isCGM technology does not offer alerts and alarms but rather requires the user to manually scan the sensor to obtain a glucose value.

Another key difference is how users obtain and archive their data. This could be problematic for patients who tend to sleep longer than 8 h.

isCGM systems will not notify the user or the caretaker for impending hypoglycemia or hyperglycemia. The indication for nonadjunctive use for making treatment decisions is particularly important as it applies to insulin therapy dosing.

In the past, all CGM systems were indicated only for adjunctive use with SMBG to confirm current glucose levels prior to making insulin adjustments and other diabetes treatment decisions. Today, three systems carry this nonadjunctive indication: FreeStyle Libre 3637Dexcom G5 38and Dexcom G6 The current Medtronic systems require confirmatory testing with Esnsor prior to bolus insulin dosing 4041but the sensors integrated into the G, G, G, and G insulin pumps can alter basal rates without confirmation.

The Eversense sensor is also indicated for adjunctive use with confirmatory fingerstick Real-tome Confirmatory SMBG with all rtCGM and isCGM sensors is recommended when the CGM reading does not match symptoms, if there is no trend arrow displayed, or if the user suspects that the reading may be inaccurate.

In the U. Differences in accuracy are also important to distinguish between and among isCGM and rtCGM systems. Numerous laboratory studies have been conducted to assess accuracy as measured by common metrics such as mean absolute relative difference MARD.

As shown in Sensir 1there are measurable differences between isCGM and rtCGM technologies and between rtCGM systems. Moreover, all current systems are less accurate in the lower glucose ranges. However, it is difficult to draw direct comparisons between systems owing to differences in study designs, methodologies, metrics, and other factors used in the various studies.

For example, there is no standardization in reporting sensor accuracy in the lower glucose ranges, which further confounds reliable comparisons. Both the Dexcom G6 and FreeStyle Libre systems are factory calibrated, which eliminates the need for daily calibration with SMBG.

Seeing glucose levels in real time can help you make more informed decisions throughout the day about how to balance your food, physical activity, and medicines.

The best option for you if you do not prefer pricking via blood sugar test machine options is to go for Freestyle Libre CGM. The device can constantly track sugar levels, which can be checked with a non-invasive scanner for instant level checking. A finger prick can be required in the case where glucose readings do not match symptoms.

Two hormones, glucagon and insulin regulate the blood glucose level in our body. Glucagon, a peptide hormone secreted by the pancreas, raises blood glucose levels.

Its effect is opposite to insulin, which lowers blood glucose levels. When it reaches the liver, glucagon stimulates glycolysis, the breakdown of glycogen, and the export of glucose into the circulation. You can buy a CGM solution through MyDiagnostics. Our platform offers the best medical devices, testing kits, and healthcare products that are designed for optimal results.

The Freestyle sugar test machine price is at INR , and can be ordered via our platform conveniently. You also benefit from complete transparency in reporting, so that you have better control over your blood glucose levels through continuous monitoring.

You should be mindful of excessive sweating, feeling dizzy, extreme hunger, and sudden mood swing if you are prone to low sugar levels. Chronic headaches, tingling lips, trembling, and heart palpations should also be taken seriously, with quick medical attention provided to the person.

Fainting can also occur, which is why instant action is key. If you have been experiencing these symptoms for an extended period, then the best option is to buy a sugar test near you. You can get one through MyDiagnostics. If you need to manage your sugar levels daily, then a continuous glucose monitoring solution is your best option.

You can get instant results with consistent monitoring, so that you can track spikes and dips in sugar levels for more clarity in reporting. Regularly taking your medication and tracking your sugar levels may be one of the best things you can do to manage your levels long-term.

This will also avoid crashing caused by eating processed or junk food. You may be tempted to go for a juice, sugary drink, or alternatives to water when you are thirsty. You should prepare in advance for these situations and carry your own water to remain hydrated.

You can manage your sugar levels regularly through active lifestyle choices. Exercising, yoga, meditation, and other methods can help you maintain better control over your sugar levels. There are several advantages and disadvantages of using a glucometer and test strips for continuous measurement of your levels.

A diabetes check machine or glucometer may be painful for many individuals with diabetes, as they may not prefer a pricking method each time. There may be a higher risk of infection, skin issues, irritation, and other problems with constant skin pricking for checking levels.

The end result of these may be non-compliance and the person not preferring to check their sugar levels regularly.

The 10 Best Glucose Meters of 2024

The manufacturer, Senseonics, a publicly traded company, started experiencing challenges in Senseonics has scaled back its workforce but continues to support the Eversense system. Like the FreeStyle Libre, Eversense measures interstitial fluids via a sensor applied to your upper arm.

The key difference is that the sensor is implanted subcutaneously, or under the skin, and is worn for 90 days at a time. Once the sensor is applied, the Eversense system sends data to your smart device automatically every 5 minutes.

It also alerts you via a vibration alarm if your blood glucose falls out of your ideal range. Overall, users appreciate how this sensor is changed every 90 days versus 7 to 14 days like other brands.

However, some have experienced sensitivity alerts when wearing the sensor in direct sunlight. The PROMISE study evaluated the Eversense, concluding that the monitor sustained accuracy and safety up to days. Like the FreeStyle Libre and Eversense, the Guardian Connect sensor is worn on your arm to measure glucose via interstitial fluids.

But unlike any other CGM currently on the market, the Guardian Connect compiles time in range data. This data tells you how long your glucose is in your personal ideal range on any given day.

You also need to change out your sensor every 7 days. This straightforward product allows you to program four reminder alarms, and the results can be processed in as quickly as 4 seconds. You can also store up to test results on the device. The TrueMetrix meter is available at Rite Aid stores and online without a prescription.

Keep in mind that you will also need to purchase lancets and test strips separately, both of which Rite Aid also sells.

Similar to the Rite Aid TrueMetrix glucose meter, this version from Walgreens uses blood samples via a traditional finger-sticking process. What sets it apart from the original TrueMetrix is its Bluetooth capabilities to deliver results to your smartphone.

It works on both Android 4. Additionally, this Bluetooth version allows you to store twice as many test results: 1, at a time.

It claims to process your results in about 4 seconds. In addition to the cost of the meter, you will still need to buy lancets and test strips from the same brand.

Walgreens sells the meter and accessories without a prescription. You may consider the Libre, G6, Guardian Connect, or Eversense based on their features, as well as the accuracy and duration of sensor wear. While most insurance and Medicare do cover CGMs, these monitors are more expensive overall.

Depending on your insurance, they may offer coverage for one type of CGM but not another. With a prescription, you may be able to buy a CGM from a medical supply store online. If you do decide to purchase a glucose meter or monitor online, be sure you know the total costs up front, including any test strips, extra sensors, lancets, and accessories that may be sold separately.

However, you do need one for a continuous glucose monitor. Some smartwatches can connect to CGM systems, allowing you to check your readings on your watch. But none are capable of taking blood glucose readings directly.

These seven glucose meters offer benefits — and some drawbacks — to consider when making your ultimate selection. You can also talk about these monitors with your doctor.

Updated Jan. Read how we test products and services. Consider whether you want to connect your continuous glucose monitor to your phone, to a receiver a small device that reads and displays your data , or both.

Look at how often the continuous glucose monitor scans and transmits your glucose levels to your phone or receiver. This can vary from a week or two, to a few months. You may want to limit your search to continuous glucose monitors that your insurance, Medicare or Medicaid will cover.

What to consider. Scan frequency. Test type. Insurance coverage. Monitoring blood glucose levels is a necessary part of daily for people with Type 1 or Type 2 diabetes. The traditional method of pricking your finger to check your blood glucose levels isn't convenient for most people, but thankfully there's an alternative: a continuous glucose monitor, or CGM, is designed to be worn and used over long periods of time.

It can make checking your blood sugar levels as simple as checking your phone. Continuous glucose monitoring devices can potentially be worn on the belly or the arm and may help you make decisions throughout the day based on your blood glucose readings, which can help with managing diabetes.

We consulted doctors and researched the most popular models to curate the best continuous glucose monitors on the market. Just be sure to talk to your doctor about diabetes monitor options to make a plan for the best health monitoring for you.

This meter is recommended by Dr. Nate Favini, medical lead of Forward. Note from Jan. This sensor is smaller than the Libre 2 and has readings sent directly to your smart phone every minute, along with other perks.

Though continuous glucose monitors are more expensive, they can help you understand what types of food and exercise are best for you. To read your blood sugar on the Freestyle Libre, you do a quick scan with the CGM device to get a reading.

There's also optional alarms if your blood sugar gets too high or too low. Rebecca Fenichel, an endocrinologist at Westmed Medical Group , and was previously recommended by Dr. Josh Emdur, medical director of SteadyMD. The Dexcom G6 doesn't require you to manually scan to get a glucose level reading -- instead you get a wireless reading either on a dedicated receiver device or to your phone or Apple Watch.

The Dexcom G6 reads your blood sugar every 5 minutes, keeping track of your blood sugar level as long as you're wearing it night and day. You can set a custom range for where you'd like your blood sugar to be, and if it goes into low blood sugar or high blood sugar ranges you set, you will get notified.

The Dexcom monitor is also approved in pregnancy and offers continuous monitoring that you can see on your phone at all times," Fenichel said. Note, Jan. This sensor is smaller than the G6 and has an improved alert system, along with a few other differences.

The Dexcom G6 is a wireless continuous glucose monitor that sends near constant readings via Bluetooth to a smartphone or watch app. Its readings are a few minutes behind, but its depth of data is like no finger stick.

If you want a device that you can set up and don't have to worry about reinserting for up to days, Eversense is a great option for diabetes management. A health care provider will insert the sensor, and then you place the transmitter above that.

Once the sensor is in place, you don't have to change it out for about days, a long sensor life. The transmitter itself can alert you if your blood sugar is too high or low, and you can also have wireless readings sent to your phone via an app.

You can share your blood glucose data from your app with your doctor or anyone else who wants to check your blood sugar readings. The Guardian Connect System is a CGM that can tell you your current glucose readings quickly via a connected app and also lets you easily access trends and data about your blood sugar over time.

One feature that stands out with The Guardian is the "predictive" alerts you can get about your sugar. Unlike other CGM systems that alert you when your sugar is already high or low, The Guardian uses technology that predicts when your blood sugar might get high or low, before it happens.

Another feature that comes with the monitor is the Sugar. IQ diabetes assistant app for diabetes management, which uses your data to help you figure out what diet, exercise and insulin works best for you.

When choosing continuous glucose monitors for this list, we look at which models were previously recommended by doctors. We also look to include a CGM that had a longer-lasting sensor life and include models that are popular choices for people with diabetes. While anyone can buy a regular blood glucose meter, you'll need a prescription from your doctor for a CGM system.

Doctors may recommend a continuous blood glucose monitoring device for reasons tied to your unique health circumstances and lifestyle, to track your personal glucose trends and keep on top of your insulin levels, but a CGM device may not work for everyone's unique diabetes care plan.

CGM devices can also give you and your doctor more information about blood sugar levels than a standard meter -- like if your blood sugar begins to drop too low, the device can warn you about your dropping blood glucose levels, "which can be a very helpful feature in helping patients avoid hypoglycemia," Fenichel said.

No, continuous glucose monitors are available only by prescription. You can get a regular glucose monitor without a doctor, however.

Many insurance plans, Medicaid or Medicare will cover a continuous glucose monitor, though they may require prior authorization.

But the cheapest way to get a continuous glucose monitor is to go through your insurance, Medicaid or Medicare -- you could potentially get one for free.

What is a CGM?

and for 90 days in the U. Numerous recent studies have demonstrated the clinical efficacy and other benefits of rtCGM use in individuals with T1D and T2D regardless of the insulin delivery method used 9 , 10 , 45 — Many of the earlier studies focused primarily on use of rtCGM in conjunction with insulin pump therapy 53 ; however, more recent studies have investigated the potential benefits of rtCGM use in conjunction with multiple daily injections MDI therapy 9 , 10 , 45 , 47 — For example, the large, randomized Multiple Daily Injections and Continuous Glucose Monitoring in Diabetes DIAMOND trial, which included T1D and T2D participants, showed that use of rtCGM improved HbA 1c , reduced time spent in the hypoglycemic T1D only and hyperglycemic ranges, and demonstrated reductions in moderate to severe hypoglycemia in individuals with MDI-treated T1D and T2D compared with traditional SMBG 9 , Improvements in diabetes-related distress and hypoglycemic confidence among the rtCGM users were also observed Recent studies have also demonstrated the benefits of rtCGM as an integrated component of sensor-augmented insulin pumps with predictive low glucose suspend functionality 54 , Automatic insulin pump suspension can help individuals with T1D avoid hypoglycemia without significantly increasing hyperglycemia, including the risk of diabetic ketoacidosis A recent single-arm pivotal trial, which included adults with T1D, showed that use of a hybrid closed-loop insulin delivery system was associated with notable reductions in time spent in the low glycemic ranges, as well as lower HbA 1c , lower variability, and improved time in target range Reduction in hypoglycemia is considered an important clinical outcome; however, the impact of rtCGM use in individuals with problematic hypoglycemia has not been widely studied until recently.

Findings from a recent randomized trial using a crossover study design assessed the impact of rtCGM versus SMBG use in T1D patients with impaired hypoglycemia awareness Investigators found that rtCGM use significantly increased time spent in normoglycemia and reduced severe hypoglycemia in this high-risk population.

The recent HypoDE Hypoglycemia in Deutschland study found similar results, reporting that use of rtCGM reduced the number of low glucose events and episodes of severe hypoglycemia in individuals with MDI-treated T1D and problematic hypoglycemia A recent head-to-head comparative study demonstrated that use of Dexcom G5 rtCGM effectively reduces time spent in hypoglycemia in MDI-treated T1D adults with impaired hypoglycemia awareness compared with isCGM use, which showed no meaningful improvement These findings lend support to the recommendations regarding T1D in adults of the National Institute for Health and Care Excellence U.

Two large randomized controlled trials have also demonstrated significant improvements in hypoglycemia, time in range, glycemic variability, and patient satisfaction in individuals with well-controlled T1D 58 and T2D 59 who were treated with intensive insulin therapy. In the Randomised Controlled Study to Evaluate the Impact of Novel Glucose Sensing Technology on Hypoglycaemia in Type 1 Diabetes IMPACT , which included participants with well-controlled T1D 6.

In addition, an increase in time spent in range and reductions in glycemic variability were also observed. The FreeStyle Libre system was also assessed in a large T2D population treated with intensive insulin therapy Randomised Controlled Study to Evaluate the Impact of Novel Glucose Sensing Technology on HbA 1c in Type 2 Diabetes [REPLACE] Reductions in HbA 1c were not seen in either of these two studies; however, smaller observational and prospective studies have shown notable improvements in both HbA 1c and hypoglycemia 60 — As discussed, there are significant differences in capabilities and limitations between and within the classes of CGM devices.

Therefore, it is important that clinicians consider the strengths and limitations of each system and how they align with the individual needs and circumstances of the patient Table 2. The following suggestions for matching patients to appropriate CGM systems are based on our professional experience as clinicians and our personal experience as individuals living with T1D.

Individuals who could benefit from data sharing capability e. It should also be considered for individuals with frequent hypoglycemia even those with adequate hypoglycemia awareness owing to the increased accuracy in the lower glucose ranges with rtCGM.

Individuals with high HbA 1c also benefit from rtCGM use Other candidates for rtCGM use include individuals who are physically active, want to use insulin pump systems that offer predictive low glucose suspend functionality, experience hypoglycemia fear, or desire tighter glucose control than obtained with their current monitoring system.

isCGM systems are especially beneficial for most patients with T2D who are not willing or able to perform SMBG as often as needed for clinical decision making.

Periodic or long-term isCGM use has potential benefits in prediabetes, patients on oral agents only, and those on basal insulin needing titration. isCGM in some of these latter patient groups could have important effects on behavior modification.

isCGM is indicated for individuals with limited risk for hypoglycemia and who do not have any degree of hypoglycemia unawareness.

Clinical benefit can be seen when patients and providers can accurately interpret and make appropriate therapy changes based on retrospective review of data.

It may also be valuable for patients who have difficulty performing fingersticks because of manual dexterity issues due to neuropathy, poor circulation to the extremities, cheiroarthropathy, or skin changes that make SMBG challenging.

isCGM is also a good option for individuals who do not need to monitor glucose values with alerts and alarms and are motivated to scan their device several times per day. In situations where cost of rtCGM is prohibitive or burdensome, isCGM may be a less costly alternative that still improves outcomes compared with SMBG alone.

Although use of isCGM could be applicable to many individuals with T2D across the natural history, no matter what type of therapy they are on, the cost and accessibility may be an issue depending on health care coverage.

In addition, SMBG still remains an important tool for many individuals with T2D. Recent advances in glucose monitoring technologies have led to the development of a new generation of CGM systems that are both accurate and reliable. Numerous clinical trials have demonstrated the safety and efficacy of these systems as stand-alone devices 9 , 10 , 45 — 52 and as integrated components of advanced insulin pump systems 54 , Based upon the growing body of supporting evidence, use of CGM is now recognized as the standard of care for individuals with T1D and a subset of those with insulin-requiring T2D 1 — 6.

Two approaches to CGM are currently available, isCGM and rtCGM. Both approaches provide patients with actionable information about their current glucose level as well as glucose trend and predictive information while avoiding the pain and inconvenience of frequent SMBG.

However, each system has its own unique features, capabilities, and limitations that must be considered when helping patients select the system that meets their individual clinical needs and life circumstances.

CGM is also an important component of the artificial pancreas backbone. CGM is currently being used with success in both commercial and do-it-yourself hybrid closed-loop systems, and there are at least five major research groups e. The authors will probably have a hard time adjusting to NOT having to count carbohydrates, determining the right insulin dose in response to anticipated food intake and exercise, dealing with hypoglycemia and hyperglycemia on a daily basis, and many other variables that cause havoc with our diabetes.

NAV v4. CGM provides information about the immediate glucose level to the user, as well as information about previous glucose trends and the current direction and rate of change. Analysis of CGM data by either the user or clinician allows for a more complete picture of glycemic patterns throughout the day and night, including not only the mean but also time in ranges and the degree of glycemic variability.

It can provide insight into the duration, frequency, and causes of fluctuations in blood glucose levels. This information can help identify and prevent unwanted periods of hypoglycemia and hyperglycemia and, thus, improve overall glycemic control 8 — Two types of CGM systems are now available: real-time rtCGM and intermittently scanned isCGM.

Current rtCGM systems automatically transmit a continuous stream of glucose data to the user in real time, provide alerts and active alarms, and transmit glucose data trend and numerical to a receiver, smart watch, or smartphone. Both CGM technologies have significant advantages over SMBG; however, differences in the features and capabilities of the two approaches must be considered when guiding patient selection of the system that meets their individual needs.

The purpose of this article is to 1 discuss the strengths and limitations of traditional methods to evaluate glucose control, 2 review the data on the currently available rtCGM and isCGM systems, 3 discuss the strengths and limitations of each CGM approach, 4 review the recent literature of isCGM and rtCGM studies, and 5 provide guidance to clinicians regarding possible clinical indications for specific patient groups.

The opinions and guidance expressed in this review are based on our clinical experiences treating diabetes patients and our personal experiences with diabetes; the authors all have been living with type 1 diabetes T1D for well over combined years.

Glycated hemoglobin HbA 1c is a validated reference marker for assessing glycemic control and predicting the risk of developing long-term complications 11 , The assay has been rigorously standardized, can be drawn in the nonfasting state, and is widely available.

As such, HbA 1c is a valuable measure of population health and is used by regulators and payers as the primary intermediate outcome measure to assess risk of developing complications and the efficacy of treatments. However, HbA 1c has limited utility in personalized diabetes management for the following reasons.

HbA 1c only provides an average of glucose levels over the previous 2—3 months, and although its value is weighted toward more recent events 13 , it does not reflect daily glucose fluctuations, variability, or time in range Likewise, does it not reflect intra- and interday glycemic excursions that may result in acute events such as hypoglycemia or postprandial hyperglycemia.

Both of these conditions have been linked to microvascular and macrovascular complications with potential interactions with other risk factors 15 , 16 ; however, the clinical impact of time in range and glycemic variability on these complications has not been fully proven in long-term clinical trials.

Nevertheless, increased glucose variability is consistently associated with mortality in the intensive care unit 17 , 18 and is a consistent predictor of hypoglycemia, both in prospective studies and within the setting of randomized clinical trials 19 , The authors can attest to the fact that glucose variability and unpredictable fluctuations are the most bothersome, dangerous, and irritating issues, none of which are captured by the HbA 1c level.

HbA 1c is an unreliable measure in patients with some types of anemia 21 , hemoglobinopathies 22 , and iron deficiency 23 , as well as during pregnancy 24 , and its correlation with mean glucose differs significantly between races Perhaps most importantly, the correlation of HbA 1c with mean glucose within individuals is highly variable even in those who do not have a condition known to alter red blood cell life 25 , There is no question that the best indicator of average glucose over the prior 2—3 months is, quite simply, the average glucose measured over the past 2—3 months.

These data are now readily available with CGM technology. Setting glycemic goals based on HbA 1c thus represents applying a population average to the individual This can lead to false reassurance in those who have a significantly higher mean glucose than expected at a given HbA 1c and potentially inappropriate treatment intensification with possible increases in hypoglycemic burden in those with lower-than-expected mean glucose at a given HbA 1c.

Therefore, even though HbA 1c is a robust and core glycemic measure, it is incomplete and potentially misleading for individual patients. Moreover, it does not provide the clinician guidance for specifically adjusting treatment regimens, particularly insulin in patients with T1D.

SMBG has traditionally been considered a key component in effective management in insulin-treated and non—insulin-treated diabetes 11 , 27 — SMBG will continue to play an important role in diabetes care worldwide for many years to come.

However, it also has inherent limitations that can impact its utility, especially in insulin-treated individuals with T1D and type 2 diabetes T2D. The requirement to perform a fingerstick to obtain a blood sample can negatively influence patient adherence to prescribed SMBG regimens.

Moreover, SMBG may not be feasible or desirable at work or school, and it is susceptible to user error due to poor testing technique, inadequate blood sample, presence of contaminating substances on fingers, and other factors 32 , all of which can lead to primarily falsely high, but also low, readings.

Additionally, postmarketing data on the accuracy and consistency of commercially available SMBG systems demonstrated that many did not meet recommended standards Because it cannot predict impending hypoglycemia or alert for hypoglycemia 34 , 35 , use of SMBG data in isolation may result in inappropriate therapy decisions.

As a result, nocturnal and asymptomatic hypoglycemia can often go undetected 34 , These issues are exacerbated during illness, stress, or major alterations in daily routine.

Similarly, our observation is that during illness severe enough to result in hospitalization, CGM provides the advantages predicted from knowing blood glucose trends. Five rtCGM sensors are currently available or being evaluated by the U.

Food and Drug Administration FDA : Medtronic Enlite and Medtronic Guardian 3 sensors Medtronic, Inc. The Medtronic Enlite sensor functions as a component of the MiniMed G, G, and G insulin pump systems, whereas the Medtronic Guardian 3 functions both as a component of the MiniMed G insulin pump system and was recently approved by the FDA for use in the U.

as a stand-alone sensor Guardian Connect. The Dexcom G5 and the recently approved G6 rtCGM sensors are stand-alone devices that can be used with both insulin pump and injection therapies, and they feature options for interoperability with numerous devices and apps.

The FDA approved use of the Dexcom G6 sensor as first in a new device category Class II Special Controls as an integrated CGM system that is compatible with other medical devices and electronic interfaces.

These devices and interfaces may include automated insulin dosing systems e. It should be noted that although the Dexcom G4 sensor is being phased out, it is still being used with the older Animas and Tandem insulin pumps.

The Medtronic and Dexcom systems utilize transcutaneous sensing and consist of three components: a disposable sensor that is inserted into the subcutaneous tissue to measure glucose levels, a transmitter that attaches to the sensor, and a receiver stand-alone device, insulin pump, smartphone, smart watch that displays and stores glucose information.

In addition, the Dexcom device can transmit data to the cloud for information sharing in real time. Guardian Connect users can opt to send text messages to care partners when they drop below their target range. Use of the Dexcom G5 with the data sharing app is now covered by Medicare. It is also our understanding that Dexcom has applied for Medicare coverage of the Dexcom G6, which as discussed earlier received FDA approval as an integrated system, and that use with the data sharing app will likely be covered.

The Eversense rtCGM system consists of an implantable, fluorescence-based, cylindrical glucose sensor 3. The Eversense system is approved in European markets and is indicated for day wear time, and it recently received FDA clearance for a day wear time in the U.

As with the Medtronic sensors, the Eversense sensor requires twice-daily calibration and is currently indicated only for adjunctive use, thus requiring verification with SMBG.

The FreeStyle Libre Flash Glucose Monitoring System Abbott Diabetes Care, Alameda, CA is the only isCGM system currently available.

After the sensor is inserted, there is a h warm-up time, and no initial or daily calibration is required during the day wear period current U. When the reader device is swiped close to the sensor, the sensor transmits a glucose level and the direction and velocity of changing glucose as well as an 8-h trend graph to the reader.

If more than 8 h pass between scans, only the most recent 8 h of data will be retained and available to the user for review. The FreeStyle Libre is indicated for nonadjunctive use and, as with Dexcom G5 and G6, the system is covered by Medicare.

Current rtCGM and isCGM devices share some common features and functions. Both technologies measure glucose concentrations in the interstitial space after subcutaneous sensor insertion, translate these values into blood glucose values for clinical use, and display current glucose values and trend information e.

Software is also available for retrospective data review and analysis. No systems have been approved for use in dialysis or critically ill patients. All systems are indicated for nonpregnant adults with T1D and T2D; however, pediatric and pregnancy indications vary Table 1.

ƒRecently approved in the U. for day wear and 1-h warm-up period. Not currently available at the time of this publication. All current rtCGM devices offer these functions, with individualized upper and lower limits, and rapidity of change alerts as well.

For example, some patients who want to be notified early can set a lower threshold alert for rising glucose as an early warning of impending hyperglycemia. This may negate the need to elevate the threshold alert in people with problematic hypoglycemia.

The Guardian Connect offers predictive high and low alerts 10—60 min ahead of time. The Eversense sensor also features predictive alerts for impending hypoglycemia. isCGM technology does not offer alerts and alarms but rather requires the user to manually scan the sensor to obtain a glucose value.

Another key difference is how users obtain and archive their data. This could be problematic for patients who tend to sleep longer than 8 h.

isCGM systems will not notify the user or the caretaker for impending hypoglycemia or hyperglycemia. The indication for nonadjunctive use for making treatment decisions is particularly important as it applies to insulin therapy dosing.

In the past, all CGM systems were indicated only for adjunctive use with SMBG to confirm current glucose levels prior to making insulin adjustments and other diabetes treatment decisions.

Today, three systems carry this nonadjunctive indication: FreeStyle Libre 36 , 37 , Dexcom G5 38 , and Dexcom G6 The current Medtronic systems require confirmatory testing with SMBG prior to bolus insulin dosing 40 , 41 , but the sensors integrated into the G, G, G, and G insulin pumps can alter basal rates without confirmation.

The Eversense sensor is also indicated for adjunctive use with confirmatory fingerstick testing Confirmatory SMBG with all rtCGM and isCGM sensors is recommended when the CGM reading does not match symptoms, if there is no trend arrow displayed, or if the user suspects that the reading may be inaccurate.

In the U. Differences in accuracy are also important to distinguish between and among isCGM and rtCGM systems. Numerous laboratory studies have been conducted to assess accuracy as measured by common metrics such as mean absolute relative difference MARD.

As shown in Table 1 , there are measurable differences between isCGM and rtCGM technologies and between rtCGM systems. Moreover, all current systems are less accurate in the lower glucose ranges.

However, it is difficult to draw direct comparisons between systems owing to differences in study designs, methodologies, metrics, and other factors used in the various studies.

For example, there is no standardization in reporting sensor accuracy in the lower glucose ranges, which further confounds reliable comparisons. Both the Dexcom G6 and FreeStyle Libre systems are factory calibrated, which eliminates the need for daily calibration with SMBG.

The Dexcom G6 also allows for optional calibration with SMBG. Although factory calibration is convenient, the ability to calibrate the Dexcom G6 may be an advantage in terms of aligning the CGM values to blood glucose measurements for people who choose to perform SMBG.

The Eversense and Medtronic sensors require a minimum of two calibrations per day. Additionally, more frequent calibration has been shown to improve accuracy of some rtCGM systems.

For those patients using the G hybrid closed-loop system, a minimum of two calibrations are required; however, four or more calibrations may be needed to stay in auto mode 40 , CGM systems that cannot be recalibrated when sensor glucose values consistently do not match results from SMBG, perhaps because of a defective sensor or local problem such as excessive bleeding at the insertion site, may need to be discontinued by the user prior to their indicated wear time.

The Dexcom G5, Dexcom G6, and Eversense systems offer the ability to share real-time glucose data with family members, caregivers, and clinicians. Data sharing also provides a safety net for elderly patients and adults who frequently travel alone.

Importantly, Medicare beneficiaries can now use their smartphones to monitor and share their CGM data. The FreeStyle Libre outside the U. The FreeStyle Libre system offers a day U. to day outside the U. wear life Table 1.

The Dexcom G5 and G6 offer a 7-day and day wear life, respectively. The Enlite and Guardian sensors have 6- and 7-day wear, respectively. The Eversense sensor, which requires an office-based procedure to insert the sensor in the subcutaneous tissue, is currently indicated for up to days outside the U.

and for 90 days in the U. Numerous recent studies have demonstrated the clinical efficacy and other benefits of rtCGM use in individuals with T1D and T2D regardless of the insulin delivery method used 9 , 10 , 45 — Many of the earlier studies focused primarily on use of rtCGM in conjunction with insulin pump therapy 53 ; however, more recent studies have investigated the potential benefits of rtCGM use in conjunction with multiple daily injections MDI therapy 9 , 10 , 45 , 47 — For example, the large, randomized Multiple Daily Injections and Continuous Glucose Monitoring in Diabetes DIAMOND trial, which included T1D and T2D participants, showed that use of rtCGM improved HbA 1c , reduced time spent in the hypoglycemic T1D only and hyperglycemic ranges, and demonstrated reductions in moderate to severe hypoglycemia in individuals with MDI-treated T1D and T2D compared with traditional SMBG 9 , Improvements in diabetes-related distress and hypoglycemic confidence among the rtCGM users were also observed Recent studies have also demonstrated the benefits of rtCGM as an integrated component of sensor-augmented insulin pumps with predictive low glucose suspend functionality 54 , Automatic insulin pump suspension can help individuals with T1D avoid hypoglycemia without significantly increasing hyperglycemia, including the risk of diabetic ketoacidosis A recent single-arm pivotal trial, which included adults with T1D, showed that use of a hybrid closed-loop insulin delivery system was associated with notable reductions in time spent in the low glycemic ranges, as well as lower HbA 1c , lower variability, and improved time in target range Reduction in hypoglycemia is considered an important clinical outcome; however, the impact of rtCGM use in individuals with problematic hypoglycemia has not been widely studied until recently.

Findings from a recent randomized trial using a crossover study design assessed the impact of rtCGM versus SMBG use in T1D patients with impaired hypoglycemia awareness Investigators found that rtCGM use significantly increased time spent in normoglycemia and reduced severe hypoglycemia in this high-risk population.

The recent HypoDE Hypoglycemia in Deutschland study found similar results, reporting that use of rtCGM reduced the number of low glucose events and episodes of severe hypoglycemia in individuals with MDI-treated T1D and problematic hypoglycemia A recent head-to-head comparative study demonstrated that use of Dexcom G5 rtCGM effectively reduces time spent in hypoglycemia in MDI-treated T1D adults with impaired hypoglycemia awareness compared with isCGM use, which showed no meaningful improvement These findings lend support to the recommendations regarding T1D in adults of the National Institute for Health and Care Excellence U.

Two large randomized controlled trials have also demonstrated significant improvements in hypoglycemia, time in range, glycemic variability, and patient satisfaction in individuals with well-controlled T1D 58 and T2D 59 who were treated with intensive insulin therapy.

In the Randomised Controlled Study to Evaluate the Impact of Novel Glucose Sensing Technology on Hypoglycaemia in Type 1 Diabetes IMPACT , which included participants with well-controlled T1D 6. In addition, an increase in time spent in range and reductions in glycemic variability were also observed.

The FreeStyle Libre system was also assessed in a large T2D population treated with intensive insulin therapy Randomised Controlled Study to Evaluate the Impact of Novel Glucose Sensing Technology on HbA 1c in Type 2 Diabetes [REPLACE] Reductions in HbA 1c were not seen in either of these two studies; however, smaller observational and prospective studies have shown notable improvements in both HbA 1c and hypoglycemia 60 — As discussed, there are significant differences in capabilities and limitations between and within the classes of CGM devices.

Therefore, it is important that clinicians consider the strengths and limitations of each system and how they align with the individual needs and circumstances of the patient Table 2. The following suggestions for matching patients to appropriate CGM systems are based on our professional experience as clinicians and our personal experience as individuals living with T1D.

Individuals who could benefit from data sharing capability e. It should also be considered for individuals with frequent hypoglycemia even those with adequate hypoglycemia awareness owing to the increased accuracy in the lower glucose ranges with rtCGM. Individuals with high HbA 1c also benefit from rtCGM use Other candidates for rtCGM use include individuals who are physically active, want to use insulin pump systems that offer predictive low glucose suspend functionality, experience hypoglycemia fear, or desire tighter glucose control than obtained with their current monitoring system.

isCGM systems are especially beneficial for most patients with T2D who are not willing or able to perform SMBG as often as needed for clinical decision making. Periodic or long-term isCGM use has potential benefits in prediabetes, patients on oral agents only, and those on basal insulin needing titration.

isCGM in some of these latter patient groups could have important effects on behavior modification. isCGM is indicated for individuals with limited risk for hypoglycemia and who do not have any degree of hypoglycemia unawareness. Clinical benefit can be seen when patients and providers can accurately interpret and make appropriate therapy changes based on retrospective review of data.

It may also be valuable for patients who have difficulty performing fingersticks because of manual dexterity issues due to neuropathy, poor circulation to the extremities, cheiroarthropathy, or skin changes that make SMBG challenging.

isCGM is also a good option for individuals who do not need to monitor glucose values with alerts and alarms and are motivated to scan their device several times per day. In situations where cost of rtCGM is prohibitive or burdensome, isCGM may be a less costly alternative that still improves outcomes compared with SMBG alone.

Although use of isCGM could be applicable to many individuals with T2D across the natural history, no matter what type of therapy they are on, the cost and accessibility may be an issue depending on health care coverage.

In addition, SMBG still remains an important tool for many individuals with T2D. Recent advances in glucose monitoring technologies have led to the development of a new generation of CGM systems that are both accurate and reliable.

Numerous clinical trials have demonstrated the safety and efficacy of these systems as stand-alone devices 9 , 10 , 45 — 52 and as integrated components of advanced insulin pump systems 54 , Based upon the growing body of supporting evidence, use of CGM is now recognized as the standard of care for individuals with T1D and a subset of those with insulin-requiring T2D 1 — 6.

Two approaches to CGM are currently available, isCGM and rtCGM. Both approaches provide patients with actionable information about their current glucose level as well as glucose trend and predictive information while avoiding the pain and inconvenience of frequent SMBG. However, each system has its own unique features, capabilities, and limitations that must be considered when helping patients select the system that meets their individual clinical needs and life circumstances.

CGM is also an important component of the artificial pancreas backbone. CGM is currently being used with success in both commercial and do-it-yourself hybrid closed-loop systems, and there are at least five major research groups e.

The authors will probably have a hard time adjusting to NOT having to count carbohydrates, determining the right insulin dose in response to anticipated food intake and exercise, dealing with hypoglycemia and hyperglycemia on a daily basis, and many other variables that cause havoc with our diabetes.
