Comparison of five commercial kits for the determination of glycosylated haemoglobin.

Five commercial chromatography kits for the measurement of glycosylated haemoglobin have been compared using blood specimens obtained from diabetic patients and from non-diabetic controls. Assessment was based on accuracy, general impressions of practicality, and overall performance. The precision of each technique was assessed by selecting five diabetic and five non-diabetic specimens and testing each one by each technique. All systems tested were of a high standard and the advantages and disadvantages of each system are discussed.
