Glucose monitoring devices -
Some doctors may recommend you test only a few times a day, while others may think continuous monitoring is more appropriate — each situation is unique and may change over time. With all the options available on the market, selecting a great glucose monitor can be a challenge.
To make the process easier, we rounded up the seven best glucose monitors available. Feel free to discuss these options with your doctor before you get started. Above all, we included glucose meters that are reportedly the most accurate.
While no home test will be as accurate as a lab version, getting as close as possible to the quality of such tests can help provide peace of mind as well as better diabetes management. We included glucose meters across a variety of features and prices.
The cost of continuous glucose monitors CGMs and blood glucose meters can vary widely based on their features, your insurance coverage, and location. Cost is also subject to change over time based on the type of insurance you have, so be sure to check with your carrier for the most accurate price.
The meter can read your glucose in as little as 5 seconds. It helps prevent wasting test strips and saves you money in the long run. The smartlight feature provides near-instant blood glucose results by displaying green, amber, or red lights to indicate above, within, or below your target range.
Contour also has an easy-to-use smartphone app that supports diabetes self-management, by adding insight and meaning to your results that sync automatically through Bluetooth. Nutrisense is designed for anyone who wants to learn more about their blood glucose levels.
The company takes care of the CGM prescription and provides you with access to one-on-one support from a nutritionist. The Signos system is a subscription plan that gives you access to a CGM and numerous health tracking features. The CGM included with a Signos plan provides real-time glucose data.
After a calibration period, the Signos app can provide personalized nutrition recommendations, including when and what to eat to manage unstable glucose levels.
The Signos system integrates with the Apple Watch, allowing you to track your nutrition, sleep, and activity in a single app. Signos leans heavily into weight loss promotion territory. Levels is an app that uses CGM data to provide users with insights into how their diet affects their health.
The app supplies real-time blood glucose level data and syncs with Apple Health kit. As you track your glucose levels, the app will provide daily recommendations for sleep, exercise, and stress management.
Devices that are compatible with the Levels ecosystem include Dexcom G6 and Freestyle Libre. The FreeStyle Libre first debuted on the market in Like other CGMs , it uses interstitial fluids instead of blood to measure blood glucose.
You use the Libre by wearing a sensor on your upper arm. To keep the Libre system working, you have to reapply a new sensor to your arm every 14 days. One downside to this CGM is that it can be a little confusing to keep track of their latest models that have the same names.
Some users also report inaccurate readings as well as skin irritation from applying the sensors. The Dexcom G6 is a sensor you wear on your abdomen that transmits information to a corresponding app you can download on your phone, tablet, or smartwatch. Users like the fact that the sensor transmits this data automatically every 5 minutes.
What sets the Dexcom G6 apart from other types of CGMs is its ability to complement other devices you might have for your diabetes management. These include insulin pumps. One of the most common complaints is that you have to change out your sensor every 10 days, versus longer wear on other CGM devices.
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. Our experts continually monitor the health and wellness space, and we update our articles when new information becomes available.

The two main types are blood glucose meters that use a drop of blood to check what your levels are at that moment and continuous glucose monitors CGMs that check your blood glucose regularly day or night—pick the one that works best for you and your lifestyle.
Of these two options, there are more choices than ever, from basic designs to more advanced models that have all the bells and whistles. Here are some things to consider:.
If you have type 1 or type 2 and just want to manage your blood glucose better, continuous glucose monitoring may be right for you. CGMs report your blood glucose levels in real time for example every five minutes throughout the day , alert you when your glucose hits a high or a low limit, and provide insight into glucose trends.
Learn more about continuous glucose monitoring and time in range. CGMs work through a sensor placed on your skin. It transmits readings to a small recording device. Whether you manage your diabetes with a pump, daily injections, or oral medications, a CGM can help you manage your blood glucose.
Many people with type 1 and type 2 can benefit from using a CGM. Those that would benefit the most are people that have trouble reaching and maintaining target blood glucose. CGMs are particularly useful if you often have lows and are unaware of when they happen hypoglycemia unawareness.
Even if you have a good handle on your diabetes management, you still may want to consider using a CGM for the convenience and the elimination of finger pricks. When it comes to choosing the right CGM for you, we are here to help. The important thing to know is that a pump gives you options. You can get a pump, wear it for a time, decide to stop wearing it, and restart it if you think it will fit better with your treatment—work with your insurance to match whatever works for you.
Pumps are an extra piece of hardware attached to your body. They work by closely mimicking your body's normal release of insulin. If your doctor determines that a pump is a good option for you, it's important to check with your insurance provider before you buy anything. Most insurance providers cover pumps, but sometimes they may not be covered and pumps can be expensive.

Systems can be divided Pomegranate Flower Essence to their intended Gluclse as monitorimg CGM which is Metabolism Boosting Drinks clinic-owned device and provides either retrospective or real-time glucose data and personal CGM which is patient-owned and provides real-time glucose data.
Professional CGM describes CGM data that are obtained via healthcare provider owned equipment. It does not necessarily provide the glucose results in real time, but downloads the readings after they have been collected, similar to a hour cardiac Holter monitor that provides information about cardiac rhythms after they have occurred.
This allows the health care provider to obtain relatively unbiased glucose patterns during typical everyday life.
The Endocrine Society recommendations state that professional CGM may be of benefit in adults with diabetes to detect nocturnal hypoglycemia, dawn phenomenon, postprandial hyperglycemia and to assist in management of diabetes therapies 3.
Professional CGM is more readily reimbursed than personal CGM, but interpretation of both personal and professional CGM reports by qualified healthcare professionals may be reimbursed on a monthly basis. Some personal CGM systems can be operated in a blinded fashion in order to provide professional glucose data.
The first device for reading blood glucose levels continuously was a professional CGM that was approved by the FDA in June This device was the Continuous Glucose Monitor System CGMS manufactured by Medtronic MiniMed Medtronic Diabetes, Northridge, CA 4. Since then, newer models have shown improvements in accuracy and patient acceptance.
In a meta-analysis of 22 articles, professional CGM resulted in a greater reduction in A1c The FreeStyle Libre Pro utilizes the same sensor as the Libre personal CGM.
The Libre is factory calibrated and therefore does not require self-monitored blood glucose calibrations. This may be a potential advantage since capillary blood glucose testing is subject to various system and user errors, which in addition to the physiologic lag time between blood and interstitial glucose which is magnified in the postprandial period could contribute to CGM error.
It collects up to 14 days of glucose readings, which are recorded every 15 minutes. The glucose sensor is fully disposable and a single reader is used to activate and scan multiple devices, allowing multiple patients in one office to undergo the procedure simultaneously.
Reports are obtained through the LibreView website, which offers a secure cloud-based system, or the FreeStyle Libre desktop reporting software. Reports provide daily patterns, an assessment of glucose variability and hypoglycemia risk, a daily glucose report, and an overall snapshot report.
The overall MARD Mean Absolute Relative Difference which is calculated by averaging the absolute values of relative differences between CGM measurement results and corresponding comparison method results for the FreeStyle Libre is It is important to note that sensor accuracy is lower on day 1 and in the hypoglycemia range MARD Accuracy improves and remains steady over the day wear period.
The Dexcom G6 Pro was approved by the FDA in March and is available in blinded or unblinded mode depending upon whether the goal is to observe glucose patterns without intervention, to provide immediate feedback to educate and inform patients about their medications and behaviors, or to facilitate decisions about pursuing personal CGM.
The sensor, transmitter, and receiver are essentially identical to the personal Dexcom G6 system and features expedited startup time and no calibration.
The device measures interstitial glucose levels every 5 minutes and is approved for 10 days of use. The device is downloaded using Dexcom CLARITY, a web-based software program that is also used to download and review personal data.
Data from all CGM devices can be studied retrospectively after downloading 8. It is recommended that diet, activity, symptom, and insulin data are collected during professional CGM to assist with interpretation, either via patient diary, direct entry of events into the device, or use of an accompanying app, depending on the system.
Three time periods should be analyzed. These are:. In certain special situations, targets may need to be adjusted.
Other important elements of a professional CGM analysis are shown in Table 1. An example of a patient who used CGM is presented in Figure 1.
The CGM demonstrated high glucose levels from PM to PM post-supper and low glucose levels from AM to 2AM. Recognition of these patterns allowed appropriately timed treatment interventions.

The ambulatory glucose profile AGP, Figure 2 is a standardized reporting format for glucose data that was developed by an expert panel of diabetes specialists and sponsored by the Helmsley Charitable Trust and is customized for insulin pumps or injection therapy 9.
The universal report is intended to simplify and facilitate interpretation of otherwise complex and lengthy reports with varying terminology. The AGP is currently employed by many reporting systems and consists of 3 components:.
Statistical Summary, which utilizes standard metrics and terminology to summarize the number of values, percentage of values, and time in target, above target, and below target, as well as an assessment of glucose variability.
Modal day report which collapses data from days or weeks to a single day in order to identify patterns by time of day. Data are presented graphically as 5 distribution curves, representing the median, interquartile range, and 10 th to 90 th percentiles, on the backdrop of target range.
As a measure of the quality of glycemia, the time in range TIRsimilar to the A1C is limited in its assessment of hypoglycemia. Multiple composite metrics have thus been reported However, the use of multiple metrics increases complexity and is subject to issues with collinearity.
The Glycemia Risk Index GRI is a composite metric that was developed using input from clinical experts who analyzed day tracings from adults with diabetes Bolus Insulin Graph: Combines all bolus insulin doses into one graph to make a one-day hour picture.
Each box on the graph covers 60 minutes of doses. Glucose Profile: Daily glucose profiles are combined to make a one-day hour picture. Ideally, lines would stay within grey shaded area target range. Glucose Statistics: Metrics include mean glucose, estimated A1C, glucose ranges, coefficient of variation and standard deviation.
RT-CGM devices not only display the current glucose every few minutes, but may also alert the patient for impending projected alert or actual threshold alert hyperglycemia or hypoglycemia or rate of change in glucose. By comparison, is-CGM requires patient interaction with the device to obtain readings but may still provide alerts for hypoglycemia or hyperglycemia.
While few head to head studies are available, some studies suggest greater reduction in hypoglycemia and improvement in TIR with RT-CGM compared to is-CGM in persons with type 1 diabetes 1314even up to 24 months Over time, accuracy with RT-CGM and is-CGM has improved substantially 1617 In fact, some devices, including the Dexcom and Freestyle Libre are approved for stand-alone use, meaning that under specified conditions, the device may be used to make treatment decisions without confirmatory blood glucose measure.
However, the user will still experience a tradeoff between a high alarm sensitivity and specificity for detecting hypoglycemic events, particularly where glucose levels are changing rapidly Figure 3. Current and recent glucose levels, trend information, and a visual alarm are all presented so that a patient can predict future low or high glucose excursions.
Using this information will allow the patient to take actions to spend more time in the euglycemic range and less time in the hypoglycemic or hyperglycemic ranges. This potential decrease in glycemic variability will not necessarily be reflected in an improved A1C value, which reflects mean glycemic levels.
Tradeoffs between emphasis on high sensitivity compared to emphasis on high specificity in a hypoglycemic alarm that is part of a continuous glucose monitor. The Guardian RT was used either continuously or biweekly for three months and both regimens were compared to control treatment which did not include use of CGM.
: Glucose monitoring devices| Choosing a CGM | Many people with type 1 and type 2 can benefit from using a CGM. The fee for service model is a major barrier to adapting many glucose monitoring technologies, which often require frequent feedback and treatment adjustments, efforts that are not reimbursed without an actual office visit. The use of pattern management software improves health care provider efficiency and accuracy in identifying needed therapeutic adjustments , For example, recent data from the Type 1 Diabetes Exchange demonstrates a 0.

Each monitor needs a specific test strip. Generic strips or strips for other monitors may give inaccurate readings. Always refer to your user's manual for directions. Most blood sugar monitors give accurate results if used correctly. Most give results within seconds. Some monitors can also talk. They give directions and results that you can hear. This is helpful if you have vision problems. Or if you have physical problems that make it hard for you to see the results. Some monitors can give spoken directions in Spanish and other languages. Some monitoring devices can monitor blood sugar continuously for several days at a time. You may be able to set an alarm on the device. This can warn you if you blood sugar gets too low or too high. You may have to check your blood sugar levels 4 or more times a day. Blood sugar levels can be affected by several things. These include:. Some blood sugar monitors can store your results. You may be able to send this information to your healthcare provider's office electronically. You can also send this information to your home computer or mobile device. One advantage of this type of monitor is that it can show you your blood sugar levels as a graph. Mobile blood sugar monitoring apps are also available for tracking and sharing blood sugar results. A finger prick can become painful and difficult if you need to do this on a regular basis. Several devices that don't need a blood sample are being developed. But most of these have not been approved by the FDA. Some of these devices use one of the following ways to measure blood sugar:. To find out if a monitor is approved for use, check the FDA website's section on blood glucose monitoring devices.
