HbA1C
Quantitative determination of Hemoglobin A1c (HbA1c) in human blood by turbidimetric immunoassay. The determination of HbA1c is most commonly performed for the evaluation of glycemic control in diabetes mellitus. HbA1c values provide an indication of glucose levels over the preceding 4-8 weeks. A higher HbA1c value indicates poorer glycemic control.

Clinical Significance
Throughout the circulatory life of the red cell, HbA1c is formed continuously by the adduction of glucose to the N-terminal of the haemoglobin beta chain. The process, which is non-enzymatic, reflects the average exposure of haemoglobin to glucose over an extended period. In a classical study, Trivelli et al. showed HbA1c in diabetic subjects to be elevated 2-3 folds over the levels found in normal individuals. Several investigators have recommended that HbA1c serves as an indicator of metabolic control of the diabetic, since HbA1c levels approach normal values for diabetics in metabolic control. HbA1c has been defined operationally as the “fast fraction” haemoglobins (HbA1a, A1b, A1c) that elute first during column chromatography with cation-exchange resins. The nonglycosylated haemoglobin, which consists of the bulk of the haemoglobin has been designated HbA0.
Test Principle
This method utilises the interaction of antigen and antibody to determine the HbA1c in whole EDTA blood. HbA1c in test samples is absorbed onto the surface of latex particles, which react with Anti-HbA1c (antigen-antibody reaction) and gives agglutination. The amount of agglutination is measured as absorbance. The HbA1c value is obtained from a calibration curve.
