About Our Hemoglobin A1c Test

Note: Fasting is not required for this test.

The Hemoglobin A1c (glycohemoglobin; glycated hemoglobin or hgb A1C) test evaluates the average amount of glucose in the blood over the past 8-12 weeks.

The glycated hemoglobin (A1c) blood test measures how thick the coat of glucose is that is bound to the blood's hemoglobin. When the two bind, the hemoglobin gets a coat of sugar around it. The coat thickens as the amount of glucose in the blood increases. The hemoglobin A1c test measure for HbA1c, a subtype of hemoglobin, specifically.

The hemoglobin A1c test measures how well diabetes is being controlled. This test is used primarily to monitor diabetes and its treatment. It measures the average plasma glucose concentration over lengths of time.


Hemoglobin A1c is observed to be lower in healthy pregnant women than healthy non-pregnant women.
