Special Features Of A Cgm
CGMs are always on and recording glucose levelswhether youre showering, working, exercising, or sleeping. Many CGMs have special features that work with information from your glucose readings:
- An alarm can sound when your glucose level goes too low or too high.
- You can note your meals, physical activity, and medicines in a CGM device, too, alongside your glucose levels.
- You can download data to a computer or smart device to more easily see your glucose trends.
Some models can send information right away to a second persons smartphoneperhaps a parent, partner, or caregiver. For example, if a childs glucose drops dangerously low overnight, the CGM could be set to wake a parent in the next room.
Currently, one CGM model is approved for treatment decisions, the Dexcom G5 Mobile. That means you can make changes to your diabetes care plan based on CGM results alone. With other models, you must first confirm a CGM reading with a finger-stick blood glucose test before you take insulin or treat hypoglycemia.
Device Interoperability And Diy Innovation
As the diabetes device industry works toward connected artificial pancreas systems, the FDA has created an entire pathway toward interoperability, or the idea of plug and play that allows various CGMs, insulin pumps, insulin pens, and controlling algorithms to work together in a modular fashion.
The Dexcom G6 was first to obtain the FDAs new iCGM designation , meaning its approved for use with similar devices that have a comparable interoperability designation like Tandems t:slim X2 insulin pump.
Dexcom now works with several devices, from the Tandem pump to the Omnipod tubeless patch pump and InPen smart insulin pen from Companion Medical. The company also has more partnerships with different diabetes data platforms than any of its competitors.
Dexcom has also been a catalyst to the emerging Do-It-Yourself diabetes technology community. It was Dexcoms CGM tech that served as the basis for a surge of grassroots innovation that crystallized at the #WeAreNotWaiting movement in 2013.
A small group of enterprising DIYers figured out a way to set up open-source data platforms to bypass the Dexcom limitations at the time. In doing so, they created the data-sharing platform known as Nightscout and an entire online community of DIY data-sharers eventually, that evolved into an open-source closed loop system, as well.
While the previous G4 and G5 versions were officially discontinued in June 2020, youll still likely find users out there holding onto these older models.

What Is Continuous Glucose Monitoring
Continuous glucose monitoring automatically tracks blood glucose levels, also called blood sugar, throughout the day and night. You can see your glucose level anytime at a glance. You can also review how your glucose changes over a few hours or days to see trends. 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.
How To Check Glucose Levels Without Drawing Blood
This is really exciting news, and not just for diabetic patients. Everyone needs to take care of their health and monitoring glucose levels is essential.
What were talking about is a free health app that lets you check glucose levels without drawing blood. The app is called Epic Health and will be released sometime before the end of the year for both Android and iOS gadgets. Its currently going through clinical trials.
The app not only gives the user the ability to accurately measure blood glucose levels, but it also measures Insulin Resistance levels. This is key in determining if you are pre-diabetic. Watch the following video for a brief demonstration.

What To Look For
If youve used a traditional glucose monitor in the past and are looking for a less painful, more portable option, then a CGM may be a better choice. You may consider the Libre, G6, Guardian Connect, or Eversense based on their features, as well the accuracy and duration of sensor wear.
While 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. Its important to check these details with your provider ahead of time.
If you dont have insurance, you can check with your doctor or pharmacist for discounts on your CGM and accessories. Its also possible to get coupons directly from the manufacturer to help offset the costs.
What Is An Iphone Glucose Meter
Apple Inc. now sells glucose monitors that can integrate with iPhones to provide people living with diabetes a better and easier way to monitor their blood glucose.
People living with such conditions can now check, control, and share the results of their blood sugar conveniently on their iPhones.
The most recent available iPhone glucose meter uses Bluetooth technology to send the results of blood sugar to these devices wirelessly using a mobile app.
Users are also able to view their major information just at a glance, which includes color-coded bar graphs displaying results percentage, an average of 14 days blood glucose readings, and below and above the users personalized target range.
Also, users can access automatic electronic logbook that displays test reading over a period of two weeks. And, even other features that enable users to enter and see information about physical activities, carbohydrate consumed and medication.
And with the data sharing feature of the mobile app, users can share major information with their caregivers, healthcare professionals, or their family members through email or text messages.
But, is that all iPhone glucometers offer? Not at all!
Here the list of other features which make the difference.

Whats A Blood Glucose Meter
A blood glucose meter is a small, portable machine that measures the amount of glucose in the blood. You place a drop of blood taken from a fingerstick and put it on a test strip, which you insert into the meter. The meter tells your childs blood sugar now, as you do the test.
Many types of meters are available. The care team will help you find the meter that is best for your child, and theyll show you how to use it. Blood glucose meters vary by:
- Cost. Ask your insurance company which blood glucose meters they cover. Its also good to ask about your coverage for test strips.
- User-friendliness. Choose a meter that is easy to use and take care of.
- Special features. Meters come in different sizes. Some can store extra information like dates, times, food intake, and exercise. Others can download readings so your provider can easily see this information.
Future Closed Loop Technology
Abbott has signed multiple development agreements with partners allowing its Libre monitor to work with future closed loop, or Automated Insulin Delivery systems.
In June 2020, the Food and Drug Administration granted the Libre 2 a special iCGM designation, meaning it has the potential to work with other pieces of diabetes technology, although unlike the similar designation granted to the Dexcom G6, Libre 2 is not supposed to be used with insulin delivery systems.
Most believe this is because the Libre 2 doesnt offer real-time continuous data as the G6 does, but requires follow-up scanning for Highs or Lows to get an actual reading for treatment. Most likely, the new Libre 3 will receive the full iCGM designation soon after its launch in the U.S.
Once that door opens, well likely see the Libre 3 paired with technology such as Tandems t:slim X2 insulin pump that has also has interoperability clearance, as well as future automated systems from developers like Bigfoot Biomedical.
With all this Libre tech in the pipeline, itll be fascinating to see what Abbott Diabetes Care brings next for improving life with diabetes.

Why You Still Need Some Finger Prick Checks
You may need to do a finger prick check, for example, if what youre feeling doesnt match what your blood sugar reading says. Or if youre treating a hypo, you may want to do one to get the most accurate result.
With some CGMs, you may also need the result of a finger prick check every day to reset your device.
How To Check Blood Sugar Without A Meter
Diabetes is a chronic condition where the body either doesnt make enough insulin or doesnt use insulin properly or both. This can lead to a higher than normal blood sugar level.
Uncontrolled blood sugar levels can lead to complications, such as:
For these reasons, its important to monitor your blood sugar if you have diabetes.
Prior to using meters, people with diabetes would monitor their blood sugar by testing their urine. This method, however, wasnt as accurate, nor did it provide real-time results.
If you self-test your blood sugar several times a day using a glucometer, or meter, it requires that you prick your finger to draw blood to test. Due to the discomfort of this method, you might look for a way to monitor your level without this tool.
If finger pricks are very bothersome for you, dont worry theres hope. Advances in blood sugar monitoring technology could mean no more finger pricks in the future.
If you have diabetes, there are several portable devices you can use to check your blood sugar level and not all of them require a finger prick.

How Does A Glucometer Work
A glucometer measures the amount of sugar in a small drop of your blood. This is done by a process called electrochemical sensing.
To get a reading, you need to prick your finger with a small needle . This will draw a small drop of blood. You then place this drop of blood on a test strip. The test strip is then inserted into the blood glucose meter. The glucometer will then give you a reading within seconds.
It is important to know that the results of a blood glucose meter are not always 100% accurate. Therefore, you should have your blood glucose level checked by a doctor at least twice a year.
Diabetes Testing And Monitoring
If you have diabetes, blood glucose monitoring can help you keep your glucose levels within a target range by balancing food, exercise and insulin, reducing your chances of diabetes complications. A range of testing and monitoring equipment is available to help people manage their diabetes. Your doctor or diabetes nurse or educator can advise you on the most appropriate equipment for you and your situation.
The Royal Australian College of General Practitioners recommends that if you have type 2 diabetes and take oral medication only, you should talk to your doctor or specialist about the need to test your blood sugar levels at home, as most people in this situation do not need to do this type of monitoring.

How Does A Continuous Glucose Monitor Work
A CGM works through a tiny sensor inserted under your skin, usually on your belly or arm. The sensor measures your interstitial glucose level, which is the glucose found in the fluid between the cells. The sensor tests glucose every few minutes. A transmitter wirelessly sends the information to a monitor.
The monitor may be part of an insulin pump or a separate device, which you might carry in a pocket or purse. Some CGMs send information directly to a smartphone or tablet. Several models are available and are listed in the American Diabetes Associations product guide.
