Product Comparison: Continuous Glucose Monitors
Continuous glucose monitors (CGMs) offer an easy way to keep track of your blood sugar at home or while on the go. Use this comparison tool as a guide to learn more about the features and benefits of your current monitor or to research a new one. To recommend a monitor not featured here, or if you are a monitor company representative seeking to update product information, contact support@body1.com
The monitor comparison guide allows you to research monitor features including:
  • Sensor Life: The expiration date of a sensor is usually several days, after which the CGM may not function properly.
  • Calibration Frequency: In order to maintain accuracy, CGMs need to be calibrated at the beginning of the cycle as well as throughout. CGMs requiring less frequent calibration require less user effort.
  • Sampling Interval: How frequently the monitor checks glucose levels. Those with shorter sampling intervals give more up-to-date information.
  • Probe Size: Probe size is length of the needle multiplied by the gauge of the needle. As probe size becomes smaller, the pain associated with applying the sensor may decrease.
  • Connects to Insulin Pump: Names of insulin pumps that connect with the CGM. An insulin pump that connects to your CGM may allow you to respond more quickly to rapid blood glucose changes.
The most important criteria are reported in the chart below. You can also View a Full Comparison Report (This page may not fit your screen).

I recently received this continuous glucose monitor system ad a gift from my girlfriend. I admit I was surprised to see the wireless connection .I wasn’t expecting a great deal of change compared to the previous CGM but I was pleasantly impressed to find that it measures glucose level every minute. I wear the transmitter on the back of my arm; it is barely visible and very comfortable to wear. I have to say it’s very smart that you have the possibility to set the alarm to go before the hypoglycemia occurs .This is very helpful for me since I like to exercise a lot. I use to have some problems with high values overnight but this monitor solved my problem. I like the glucose prediction feature and I find it extremely useful. I never had problems with the transmitter; I didn’t bleed when I attached it. I like the freestyle meter too. It is easy to surf through the menu and easier to access the information.

As a diabetic for the past 30+ years and extremely active person, I really value this new technology. I used DexCom7 for 1 year and Medtronic for 6 months, and I hope my experiences can help you make the best choice. First, any of these is better than none. Nevertheless, I found the DexCom7 to be a far superior machine. Here is a brief summary of the pros and cons of both. DexCom Benefits Positives • More Accurate: Far superior in blood glucose results and they rarely go bad • Great customer service • Don’t need to calibrate as often • Longer sensor life - 7 day sensor • No scaring • More areas for insertion Challenges • Alarm is not very loud – at night, I used an amplifier to wake me when it rang • Alarm only rings every 30 minutes Medtronic Advantages Positives • Less equipment if using a Medtronic Pump • More Warnings of Highs and Lows Challenges • Lack of accuracy: Huge differences between the Medtronic CGM and reality. • Bad Sensors: Sensors go bad often (roughly every other sensor) and Medtronic customer service drills you when you request a replacement • Scaring – Lots more scaring • One insertion site – stomach (otherwise replacement isn’t covered) • Short sensor life –3 days I will be switching back to the DexCom. It is a far superior machine and their customer service is much better. Hope this helps you choose the best CGM.

This was my first continuous blood sugar monitor and I thought it was great when I had it, but I changed insurance and had to go with another machine to get the probes my new insurance would pay for. Anyway this machine has all the bells and whistles. It will warn you BEFORE you reach a critical blood sugar range and takes a reading every five minutes. The probes can be worn for one week and they deliver the blood sugar info which you should be withing five feet of. You hardly notice you have it on and it can be worn in the shower, pool, or while you're asleep with no difficulty at all. Overall this is a very nice system that I wuold recommend to anyone.

My Rating:
I gave the MM Paradigm CGMS a test run for 4 months last year prior to going to the Animas 2020. I didn't have great success with the CGMS - due to alarms for hypos that when verified with blood meter were incorrect (readings with CGMS are 20 mins behind real time). Also, calibration errors with the sensor - which I quickly learned how to overcome from various forums where users had tips- very annoying - found that the sensor didn't work well for me. On average a sensor lasted 24-36 hours for me (for some they can tweak them to last 15 days). At the cost of $50CDN per sensor - too expensive IMHO. I do sometimes wish I'd been abit more patient - and kept up with it - but having both infusion set AND sensor inserted into my skin - just was not my cup of tea. I know there are many satisfied MM users out there tho' unlike myself - especially those that are have hypo unawareness - or folks that like to see a graph of their BG's over a 24-hour period - to enable them to figure out probs with their insulin therapy. I'd give it a try again maybe one day on a trial basis if offered (maybe not MM but other company) - as this is still new technology and being improved all the time.
