Glycosylated hemoglobins and diabetic control assessment. 1981

M S Torre, and D H Schofield, and R A Mangione

This historical development, biosynthesis, analysis, interpretation, and utilization of glycosylated hemoglobin determinations (HbA1 or HbA1c alone) are presented. The relationship between glycosylated hemoglobin determinations and assessment of diabetic control is discussed. HbA1 and HbA1c levels are elevated approximately twofold in diabetic patients. A correlation exists between abnormal fluctuations in blood glucose levels and HbA1 concentrations. The results of glycosylated hemoglobin determinations are not influenced by recent meals, physical activity, emotional stress, or inherited abnormalities. Although glycosylated hemoglobin determinations are subject to fewer variables than blood and urine glucose assessments, the clinician must be aware of the indications and limitations for their use. These indications and limitations are discussed.

UI MeSH Term Description Entries
D003920 Diabetes Mellitus A heterogeneous group of disorders characterized by HYPERGLYCEMIA and GLUCOSE INTOLERANCE.
D006442 Glycated Hemoglobin Products of non-enzymatic reactions between GLUCOSE and HEMOGLOBIN (occurring as a minor fraction of the hemoglobin of ERYTHROCYTES.) It generally refers to glycated HEMOGLOBIN A. Hemoglobin A1c (Hb A1c) is hemoglobin A with GLYCATION on a terminal VALINE of the beta chain. Glycated hemoglobin A is used as an index of the average blood sugar level over a lifetime of erythrocytes.
