Abstract
An improved method of testing individuals for diabetes, even if they have levels of interfering substances (e.g., uric acid, bilirubin, and glutathione) that would otherwise interfere with such testing, is disclosed. The individual's protein-bound glucose level and glucose level are compared to the analogous values for a reference population to enable the risk of that individual's having diabetes to be assessed. The substances that would otherwise tend to interfere with the assay for protein-bound glucose are removed before the assay, desirably by precipitating the protein-bound glucose using uranyl acetate, which desirably leaves substantially all of the interfering substances in the supernatant, then separating the precipitate from the supernatant, redissolving the precipitate, and conducting the colorimetric assay on the resulting solution. An improved colorimetric test for protein-bound glucose using viologens as the colorimetric electron acceptors is also disclosed.
