Finger-prick glucose monitor -
An isCGM also has several parts. The other part is a wireless reader device that displays your glucose level when the sensor is scanned with the reader device or smartphone app. You can get a reading when you need it on demand. There can be a 5 to 15 minute difference between an interstitial glucose level and a blood glucose level.
If your glucose levels are not changing quickly there may be little difference between your interstitial glucose level and your blood glucose level. But when your glucose level is changing quickly, like after eating a meal or treating a low blood glucose, there can be delays in getting an accurate reading from your CGM.
At any time, you can look at the receiver or smartphone app and see your glucose level. You can see if your level is going up or down—and how fast. You can see the trends and patterns of your glucose levels. Some monitors use apps and websites to show you trends and patterns. Some monitors let you add notes of when you eat, exercise, and take medicine.
That way you can see how those activities affect your blood glucose levels throughout the day and night. All this detailed information gives you and your diabetes care team a better idea of your treatment needs.
Some rtCGMs and isCGMs need you to poke your finger and use your CBG meter to confirm what the monitor is telling you. Anytime your rtCGM or isCGM does not display a value, or if the reading does not match your symptoms, it is recommended that you verify the rtCGM or isCGM result with your finger poke CBG meter to make sure your sensor is reading accurately.
An rtCGM or isCGM is constantly measuring your blood glucose levels. This information helps some people who have diabetes make decisions about what to eat, how or when to exercise, and how much medicine to take. Some rtCGMs and isCGMs have an alarm feature to alert you if your blood glucose level is quickly going up or down, or if you have a blood glucose level out of your target range.
This is helpful for people who have problems knowing when they have low blood glucose hypoglycemic unawareness. Some monitors can be set up so that parents, partners, or caregivers can be alerted when your blood glucose is dropping quickly while you are asleep.
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. VIEW ALL HISTORY.

It tracks your blood sugar level during the day and night. This can help you make better choices about food, physical activities, and taking medicines. It can also find trends and patterns that can help your healthcare provider better manage your diabetes.
Besides giving you your blood sugar at any moment, CGM also gives you the percentage of time your blood sugar has been in the normal range or too high or too low. This percentage is called time in range TIM.
These target numbers are adjustable according to your age and other conditions. CGM is a safe, effective treatment for people with type 1 diabetes and for certain people with type 2 diabetes.
CGM devices should be considered soon after diagnosis of diabetes that requires insulin management. They are ideal for people who need to have tight blood sugar control to keep blood sugar from getting too high or too low.
Thy are also helpful for people who may not recognize symptoms of low blood sugar. Ask your healthcare provider if CGM is right for you. Several CGM devices are available. They are approved by the FDA with a prescription from a healthcare provider.
The devices have a sensor, transmitter, and a receiver or monitor. The sensor is a small device placed under the skin. It will measure your blood sugar several times a minute. A transmitter sends the information to a receiver.
This may be a part of an insulin pump or a separate device. Your blood sugar may still need to be checked a few times a day with a regular glucose meter to check for accuracy.
With most CGM models, the sensor under the skin needs to be replaced every 7 to 14 days. At least 1 model uses a sensor that is implanted under the skin and can function for up to days. Implanted sensors must be placed and removed by your healthcare provider.

Check with your insurance company to find out if blood glucose monitoring equipment and testing supplies are covered under your plan.
If not, many suppliers offer rebates or discounted prices on trade-ins. In addition, when selecting a glucose meter, the ADA reminds consumers to factor in the ongoing cost of test strips.
