Abstract

Techniques for affinity measurement of glycated albumin and for glycated total plasma protein have been developed. The two techniques were contrasted. Both techniques are linear over a 100-fold range of sample concentrations. There appears to be a non-specific early glucose binding phase to non-albumin plasma proteins. Although this phase is detected by radioactive incorporation and thiobarbituric acid, it does not interfere with the affinity determination, which does not appear to detect the early binding species. The correlation of glycated albumin levels with glycated hemoglobin levels is much stronger than that of glycated globulin levels with glycated hemoglobin levels. Due to the large contribution of glycated albumin levels to total glycated serum protein levels, the correlation of the latter with glycated hemoglobin levels is sufficiently strong to allow the use of either technique as an adequate index of glycation.
