The amount of HbA1c formed is directly related to the amount of glucose in your blood. Red blood cells live for an average of 120 days, so HbA1c gives an indication of how much sugar there has been in your blood over the past few months.

Answered by Apollo Doctors

Sir, I recently had a fasting glucose test, which showed 103 mg/dL, and an HbA1c test, which showed 12.52 percent. Is it possible for these results to be correct together, or is there a mismatch?
