TL;DR
A precise and inexpensive method for the automated analysis of glycosylated haemoglobin based on a colorimetric technique is described, which shows good results in both within-batch and between-batch measurement.
Abstract
The measurement of glycosylated haemoglobin is now widely used as a guide to glycaemic control in patients with diabetes mellitus. Present methods for measurement of glycosylated haemoglobin are either laborious, expensive or both. We describe a precise and inexpensive method for the automated analysis of glycosylated haemoglobin based on a colorimetric technique. The within-batch coefficient of variation ranged from 2.0 to 4.8% and between-batch was less than 11.0%. At least 200 samples can be analysed per day.
