There are two versions of the True Metrix glucometer: the basic version and the Bluetooth version, called the True Metrix Air. The Air doesn't cost much more than the basic version and uses the same test strips. Both are easy to use and utilize affordable test strips that you can find in most diabetic supply stores and pharmacies. The Air can store a lot of test results and shows your average glucose levels for up to 90 days. It also has an app to help you manage your diabetes.
Test-Strip Costs & Availability
This blood glucose monitor's test strips are carried in most, but not all, of the stores we checked; you shouldn't have trouble finding them at your local pharmacy.
The average cost per strip is about 31 cents, which is among the cheapest on the market. For comparison, the most expensive strips in our review run about $1.40 each, and some of the most expensive on the market can cost over $2 per stip. The savings add up over time.
Design & Features
Each test strip uses the company's patented Triple Sense Technology, which automatically detects, analyzes and corrects variables that affect accuracy. These strips don't require coding, and you can test with a sample from your fingertip or forearm. A handy strip-release button on the face of the device ejects the strips so that you don't have to handle them after testing. The control and navigation buttons are located on the top of the meter, and for people with limited dexterity, the slim design of the buttons may make them harder to manipulate than those on other meters.
The Air has Bluetooth and pairs with your smartphone to transfer your test results to the True Manager Air app. This app tracks your data automatically and displays charts, graphics and customizable notes.
Ease of Use
The True Metrix Air uses a small blood sample of just 0.5 microliters, and it can read levels between 20 and 600 mg/dL. It can test your blood in 4 seconds or less, making it one of the fastest times in our review.
The True Metrix Air can also alert you with four different reminders, including one to check for ketones when your blood glucose test results go above a specified level, which is a common feature in the meters we reviewed. It also displays the day of the week, and its internal memory can store up to 1,000 test results, which is the largest memory of glucometers we tested.
The Final Verdict
The True Metrix Air is an accurate glucose meter, and the company touts clinical trials and testing against other well-known glucose monitors that back its accuracy claim. You can find the test strips in most stores, and they don't cost much compared to most glucometers. In addition, the Bluetooth connectivity and True Manager Air app allow you to track your data to help you manage your diabetes.
