About Our Glycohemoglobin (GHb) Test, Total
Note: Fasting is not required for this test.
The glycohemoglobin (GHb) blood test measures levels of glucose 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. There are numerous subtypes of hemoglobin, and this test is used to measure all glycosylated hemoglobin.
This test is used primarily to diagnose and monitor diabetes. Glycohemoglobin is also referred to as glycated hemoglobin.
