TRUE METRIX is a blood glucose monitoring system designed for people with diabetes who need to check their blood sugar at home. Made by Trividia Health, it delivers a reading in 4 seconds from a small drop of blood and stores up to 500 results in its built-in memory. The system includes a meter, test strips, and a lancing device, and it comes in several versions depending on whether you want basic monitoring or wireless data sharing.
How the System Works
The TRUE METRIX meter uses what the manufacturer calls Triple Sense Technology, which automatically detects, analyzes, and corrects for variables in your blood sample. This means the meter requires no manual coding. Older glucose meters needed you to enter a code from each new box of test strips to stay calibrated. Skipping or mis-entering that code was a common source of inaccurate readings. The TRUE METRIX skips that step entirely, reducing one of the most frequent user errors in home glucose testing.
The blood sample needed is just 0.5 microliters, which is roughly the size of a pinhead. You prick your fingertip with the included lancing device, touch the test strip to the drop of blood, and the meter displays your result in about 4 seconds.
Accuracy
In clinical testing submitted to the FDA, the TRUE METRIX exceeded the international accuracy standard (ISO 15197:2013) that regulators use to evaluate glucose meters. When healthcare professionals used the system, 99% of results fell within the accepted accuracy window: within 15 mg/dL for readings below 100 mg/dL, and within 15% for readings at or above 100 mg/dL. Patient self-testing produced nearly identical numbers, with 99% of results also meeting those same limits. That’s a strong showing, since the standard only requires 95% of results to fall within range.
Versions of the Meter
Trividia Health sells the system under a few different names. The base TRUE METRIX model is a straightforward meter with a screen, memory storage, and no wireless connectivity. The TRUE METRIX AIR adds Bluetooth, letting you send your stored results wirelessly to a smartphone app. The TRUE METRIX GO is a compact, portable version aimed at people who want something smaller to carry. All three versions use the same test strip technology and share the same core accuracy specs.
Tracking Your Results
Every version of the meter stores up to 500 blood glucose results with averaging and event tagging, so you can mark whether a reading was taken before a meal, after a meal, or at another specific time. That history stays on the meter even without a phone connection.
If you use the TRUE METRIX AIR, you can pair it with the TRUE MANAGER AIR app on your phone. The app pulls results from the meter’s memory over Bluetooth and organizes them into several report types:
- Logbook: A color-coded chart showing your results against your target range, sorted by day and time.
- Modal Day/Week Report: Groups all your readings into time blocks throughout the day or week, making it easier to see if mornings or evenings tend to run high or low.
- Glucose Trend Report: A customizable graph that plots readings over time so you can spot patterns visually.
- Averages Report: Shows your average blood sugar over 7, 14, 30, 60, 90, or 120 days, which is useful for tracking longer-term trends between doctor visits.
- Conformance Report: Breaks your pre-meal and post-meal results into pie charts showing what percentage fell above, within, or below your target range.
You can also share any of these reports directly with your healthcare provider, family members, or anyone else involved in managing your care.
Control Solution Testing
Like most home glucose meters, the TRUE METRIX comes with a control solution: a liquid with a known glucose concentration you apply to a test strip to verify the meter is reading accurately. The manufacturer recommends running a control test when you first open a new box of test strips, when you suspect the meter or strips may have been damaged, and periodically as part of routine maintenance. If the control result falls within the acceptable range printed on the test strip vial, your meter and strips are working correctly.
Who It’s Designed For
The TRUE METRIX is positioned as an affordable, no-frills glucose monitoring option. It’s commonly available through pharmacies and is covered by many insurance plans and Medicare suppliers, which makes it one of the more accessible meters on the market. The small sample size and fast result time make it practical for people who test multiple times a day and want to minimize discomfort. The Bluetooth-enabled AIR version adds a layer of data tracking that’s helpful if you or your doctor want to review trends over weeks or months, but the base model works fine if you just need a reliable reading in the moment.
