Buying A Cgm Or Flash Glucose Monitor

Continuous Glucose Monitoring Q& A

If you dont qualify for a flash glucose monitor or CGM, your main option is to self-fund a device. Its expensive so if its something youre thinking of doing, its worth speaking to your healthcare team first to see if they think its something that would suit you.

There is only one flash glucose monitor manufactured at the moment. This is called the Freestyle Libre . Both are offered on the NHS to people who qualify and are available to buy.

Best For: Overall Function

What makes the G6 our top pick is the fact that you donât need to âwandâ over the monitor to update your phone. What this means is that you will get a steady stream of glucose data from the CGM without having to do anything yourself. This allows for real time alerts, such as a dangerously low glucose value.

Best Glucose Meter For Built

This self monitoring blood glucose meter requires no coding, making it one of the easiest blood sugar monitors for beginners. Like the other devices featured in our best glucometers roundup, it produces fast results with minimal fuss.

The Trividia Health True Metrix Blood Glucose Meter stores approximately 500 readings, and these can be downloaded onto your computer for storage.

This meter has over 190 reviews on Amazon, scoring an average of 4.6 out of 5 stars. 89% of those are rated highly, and highlight the meters accuracy and reliability. Value for money is another common motif. Again, like all the other glucometers in this guide, a minority of reviews criticize the accuracy and battery life. From 350 reviews on Walgreens, the meter scores a lower 3.6 out of 5, with 209 being 5-star reviews, and 71 being 1-star reviews. Critical reviews state that the meter is inconsistent, while positive reviews say it has never faltered in its accuracy.

The meter offers 7-, 14-, 30-, 60- and 90-day averages to help you determine if your diabetes management routine or medication are working or need to be adjusted with your doctors guidance.

You can tag blood sugar results by linking them to specific instances such as pre- or post-meal, when taking medicine, or after exercising. The True Metrix Blood Glucose Meter has four programmable alarms to remind you to test your blood sugar levels handy if you often forget to do so and it has a ketone reminder.

Best Glucose Meters: The Final Word

Glucose meters wear out over time and should be renewed every two years to ensure accurate and reliable results. Before buying a glucose meter, check with your insurance provider to see what they will cover. That includes test strips compatible with the glucometer youre thinking of purchasing, as strips can drive up the overall cost in the long-term.

Once you know where you stand with your insurer, you can then make a shortlist of the best glucose meters within your budget range. Look for features that will make your life easier, such as a large display, or data storage for multiple readings. Keep the size in mind too, as youll be carrying your blood sugar testing kit with you throughout the day.

Ultimately, a glucose meter is only good for you if it works for your diagnosis, your lifestyle and your budget. If youre really stuck and still dont know which glucometer to choose, ask your doctor or a diabetes health expert if they can make some recommendations even a steer on brands will point you in the right direction.

Features To Look For In Blood Glucose Monitors

Blood glucose meters can come with a lot of different features and, depending on your needs, will determine the level of importance you place on these features. Your doctor or health care professional is also likely to help you when it comes to choosing the right meter for your needs.


Blood glucose meters are all quite compact in size and easily portable. Take a look at the size of the display screen on the meter. Is it large enough and are the results clearly visible for you?

Light at strip port

This can be a useful feature to easily see and help guide where the strip needs to go. It’s not a common feature among blood glucose meters, only one of the products we tested has a light strip at the port.

This is useful to easily see the screen if you need to take a reading during the night or in low light conditions.

Memory capacity

The meters we’ve tested can store anywhere from 99 to 2000 results. Being able to monitor your blood glucose levels over time is important for long-term management.

Test strips

Test strips should be very easy for you to get out of the container. In some cases the strips can tend to stick together which can become an annoyance and if they are individually wrapped they can be more time-consuming to open. An ejector for the strip could also be a useful feature.

Available software

Some meters are compatible with your mobile or smart device via Bluetooth, while a couple we’ve tested are app-based.

What About Health Insurance Coverage

Its helpful to know that the Dexcom G6, Abbott FreeStyle Libre 2, and Eversense implantable CGM are all covered by most private and public health insurance plans, including Medicare . Medtronics Guardian Connect, however, was not covered by Medicare as of December 2021.

Historically, people with type 1 diabetes have had a much easier time qualifying for a CGM through insurance than those with type 2 diabetes because it was easier to establish medical necessity.

Still, if you have T2D and your doctor can make a case for medical necessity, you may qualify. But your insurance company may still want to confirm whether you actually need a CGM.

If you can prove youre experiencing both high blood sugars and low blood sugars regularly, you will likely qualify. This can be proven by providing blood glucose logs uploaded from your fingerstick meter. Generally, hyperglycemia is defined as a blood glucose level of 250 mg/dL or over, while hypoglycemia is a blood sugar 70 mg/dL or below.

If your insurance company denies your coverage for a CGM, talk with your doctors office about peer-to-peer reviews and appeals. Pushing your doctor to fight for you matters.

Manufacturers can have your back here, too. Dexcom, for instance, has an easy-to-complete patient information form you can submit along with your insurance information. The company will then contact your insurer to work on getting your device authorized and covered. Medtronic offers a similar service.

How To Use A Glucose Meter

At first, using a glucose meter may seem overwhelming, but it becomes easier after a bit of practice.

For a standard glucometer, the Centers for Disease Control and Prevention recommends the following steps:

  • Make sure the meter is clean.
  • Remove a test strip and immediately close the strip container, as strips can get damaged easily.
  • Wash and dry your hands, and then gently massage your hand to improve blood flow.
  • Use a lancet to prick your finger. The lancet is inserted into the lancing device and set to the ideal depth to pierce the thickness of your skin. Squeeze from the base of your finger and gently place a small amount of blood onto the test strip. Always use a new, clean lancet each time.
  • Place the strip into the meter. After a few seconds, your reading will appear, typically expressed as mg/dL .
  • Record your results in a logbook or on the meters software. Add notes about anything that might have made the reading out of your target range, such as food you recently ate or any activity.
  • Properly dispose of the lancet and strip.

Where Can I Test My Blood Sugar Besides My Finger

Best continuous glucose monitors for 2021

The finger is the most reliable area for a person to test their blood sugar. However, some monitors may allow for alternate site testing. These alternate sites may include the palm, upper forearm, abdomen, calf, and thigh.

A person should always check the instructions on their blood glucose monitor to check if this is possible before performing alternate site testing.

What Supplies Do I Need

CGMs require three basic parts:

  • Sensor monitors real-time glucose levels, usually every five minutes. The sensor is inserted under the skin by the user with a simple applicator. Sensors are normally worn for 7-14 days, depending on the system. However, the new Eversense Implantable CGM system can be worn for up to 90 days.

  • Transmitter sits on top of the sensor and sends glucose information to a receiver or a smartphone app. Most systems have a transmitter that is reusable for 3-12 months. In the case of FreeStyle Libre, there is no reusable transmitter each sensor is fully disposed after 14 days and a new one is put on.

  • Smartphone app or receiver displays real-time glucose level, whether blood glucose is trending up or down, and glucose history. Most CGMs offer smartphone apps for viewing data. Abbott and Dexcom also offer handheld devices for people that dont use a smartphone. Some CGM devices also send the glucose value to an insulin pump, including a growing number that can automatically deliver insulin accordingly.
