Why does the test sometimes start even if yellow is still showing in the strip window of my Accu-Chek meter?

The system in your meter automatically detects when enough blood has been applied to the strip and begins the test, even if some yellow is still visible. The only time you need to apply more blood is when the blood drop symbol continues to flash in the display. What happens if I use expired Accu-Chek test strips in my meter? Using test strips that have expired can cause your results to be inaccurate. If your test strips have expired, throw them away and begin using a new vial of strips. The expiration date is printed on every vial of test strips.
