Description
HbA1C measurement is recommended for patients with diabetes to document the degree of glycaemia control at initial assessment, then as part of continuing care. The test is used both as an index of mean glycaemia and as a measure of risk for the development of diabetes complications.
Indications
Glycosylated Hemoglobin, HbA1c, is a term used to describe a series of stable minor Hemoglobin components formed slowly and nonenzymatically from Hemoglobin and glucose. The rate of formation of HbA1C is directly proportional to the ambient glucose concentration. Because erythrocytes are freely permeable to glucose, the level of HbA1c in a blood sample provides a glycaemia history of the previous 120 days, the average erythrocyte lifespan.
