Fructosamine: an alternative assessment of past glycaemic control in developing countries.
Fructosamine assay determines glycaemic control in diabetic patients by measuring glycosylated plasma protein. This study was done to assess the value of fructosamine as an alternative test to HbA1c as a measure of glycaemia. Sixty patients (both insulin dependent diabetes mellitus and non insulin dependent diabetes mellitus) were selected from the diabetic clinic and fasting blood samples were collected for estimation of glucose, HbA1c and fructosamine levels. The results were compared by correlation analysis and major discrepancies/discordance was detected by dividing the results into 3 clinical categories and detecting the cases in which the values fell in opposite clinical categories. Fructosamine correlated well with HbA1c (r = 0.41, p < 0.01) and with fasting blood glucose (r = 0.45 p < 0.01). Major discordance was detected in the results of only 7 patients which can partly be attributed to different periods over which HbA1c and fructosamine reflect average glycaemia. Fructosamine measures glycaemia over the past 2-3 weeks and HbA1c over 8 weeks. As fructosamine assay is relatively inexpensive, reliable and simple to perform; it can be used as an alternative to HbA1c and is particularly suited for developing countries.
