Glycated hemoglobin (HbA1c) is a form of hemoglobin which is measured primarily to identify the average plasma glucose concentration over prolonged periods of time. It is formed in a non-enzymatic glycation pathway by hemoglobin's exposure to plasma glucose. The non - glycosylated hemoglobin, which consists of the bulk of hemoglobin, has been designated HbAo. Description: Erythrocyte lysates. Alternative Names: HbA1c protein, Hemoglobin Ac 1, Hemoglobin A1c, Hemoglobin Ac 1 protein, Hemoglobin Ac-1, Hemoglobin Ac-1 protein
