What to do if Arkray GLUCOCARD Expression Blood Glucose Meter control solution test is out of range?
- NNancy HenryJul 30, 2025
If the Arkray Blood Glucose Meter control solution test is out of range, ensure you're using GLUCOCARD Expression Control Solution. Also, verify the testing environment is between 50°F to 104°F. Check the expiration dates and open bottle dates on both the control solution and test strips. Repeat the test using a new test strip and, if needed, a new bottle of control solution.
