The A1c measures the average amount of glucose that has attached to the hemoglobin in your red blood cells over the past 2 to 3 months.
Hemoglobin, a protein that gives blood its red color, carries oxygen throughout your body and is essential for maintaining good health.
Red blood cells regenerate approximately every 3 months, which is why the A1c test reflects your average blood glucose levels for this period.
The results are typically more influenced by glucose levels in the several weeks immediately preceding the test.
