Are the Duo and Nano accurate?
Yes! The Center Health Nano and Duo are of the most accurate test strip sensors in the world.
The device was cleared by the FDA's latest 2017 blood glucose monitoring guidelines, and has an operating range of 20 mg/dL to 600 mg/dL (1.1mmol/L to 33.3 mmol/L) with a hematocrit range of 20-70%.
As cited in the Duo and Nano's FDA approval, for glucose concentrations less than 75mg/dL, the Center Health sensor was within 15mg/dL of the YSI reference value 100% of the time, within 10mg/dL 98% of the time, and within 5mg/dL 42% of the time. For concentrations above 75mg/dL, the Nano was within 15% of the reference value 100% of the time, within 10% 95.5% of the time, and within 5% 52% of the time.
How are Center Health sensors able to achieve these results? Unlike normal test strips which only use one set of enzymes to measure blood sugar, the Center Health test strip has 2 sets of enzymes on every test strip. This allows for hematocrit interference to be measured and adjusted for during the 5 second blood sugar test, which enable the Duo and Nano to compute extremely accurate results.
