What should I do if my glucose readings seem inaccurate?
Readings from a blood glucose meter (BGM) and your Stelo Glucose Biosensor System might not be the exact same number.
One reason is they're measuring glucose in different fluids. The BG meter measures blood glucose while the biosensor measures interstitial fluid. If your healthcare provider did a lab test at the same time, the lab result might give you a third number. The lab test is considered the most accurate number.
Other reasons there could be a difference between your BG meter and the Stelo Glucose Biosensor System are:
- Hand cleanliness: Wash your hands with soap and water (not hand sanitizer) and dry them. Then test. Many inaccurate BG meter values are from hands not being washed thoroughly before testing.
- Biosensor's first day: With newly inserted biosensors, the differences between your BG meter and the biosensor reading might be greater. Generally, the numbers get closer over the first 24 hours.
- Pressure on biosensor: Sometimes when something is pressing on your biosensor, for example, if you're lying on it, it can affect your biosensor readings. Relieve the pressure and the numbers should get closer.
- Glucose changing quickly: When your glucose is rapidly changing, it can be more difficult to compare your BG meter value and biosensor reading because blood glucose changes a little before interstitial glucose. The numbers should get closer when your glucose stabilizes.
- Test strips: Make sure your test strips are stored as directed and not expired. Also, make sure to use enough blood on the test strip.
You can log your BG meter value in the app's Events tab.
