How to fix control solution test out of range on Prodigy Blood Glucose Meter?
- BBrittney JohnsonJul 27, 2025
If your control solution test is out of range, several factors could be the cause. Carefully read the instructions and repeat the test. Ensure the control solution bottle is shaken vigorously before testing. Check the expiration date of the control solution; if it's expired, discard it. Also, make sure the control solution is at room temperature (less than 86°F/30°C) before testing, and repeat the test with a new test strip.
