Yes, when stored per recommended storage conditions the accuracy of the biosensor remains consistent during its shelf life. Please refer to the biosensor carton and instructions for use for the expiry date and recommended storage conditions.
You can take standard doses of ascorbic acid (vitamin C). Taking higher than the maximum recommended daily allowance (RDA) of ascorbic acid may affect the biosensor readings and could make them look falsely elevated.
Readings differences can be caused by a variety of factors and some differences between biosensor glucose and blood glucose are considered normal and expected.
Biosensor and blood glucose readings can both be accurate but different, because they measure different fluids in the body. The biosensor measures glucose in the interstitial fluid; blood glucose measure glucose in the blood. Glucose enters the bloodstream first, before it is absorbed by the interstitial fluid. This difference is called lag.
- When glucose levels are stable, expect to see small differences between your biosensor and blood glucose readings.
- When glucose levels are changing rapidly (after meals or exercise, for example), expect greater differences between your biosensor and blood glucose readings.
To get the most out of your glucose biosensor, focus on both the glucose measurement and the trend.
As a reminder, the biosensor is not intended for the screening, diagnosis, treatment, cure, mitigation, prevention, or monitoring of diseases, including diabetes.
