Hemoglobin A1C Test
Monitor blood sugar with HbA1C
The hemoglobin A1C test (also known as HbA1C) is used to show the long-term changes in blood sugar. When blood sugar is elevated over a long period of time, a sugary coating called glycosylated hemoglobin develops over the surface of the red blood cell. As more of the oxygen-carrying hemoglobin is coated, it can decrease the cell’s ability to transport oxygen.
Hemoglobin A1C can be used to monitor blood sugar therapy. As daily blood sugar improves and stabilizes, Hemoglobin A1C levels should improve also.
How Often Should My Hemoglobin A1C Levels Be Tested?
The lifespan of red blood cells is approximately 120 days, therefore, it has been recommended to retest Hemoglobin A1C every 2-3 months.
