Abstract: This invention teaches a process for reducing protein matrix effects in assays for serum fructosamine. Blood or blood derived samples are used, and one adds two reagents, one of which reduces interference caused by non-specific reducing substances, the other of which eliminates turbidity. Incubation follows, and then the pH of the sample is adjusted and color forming reagent is added. In one embodiment, the incubation time is only 1-15 minutes. In another embodiment, the first reagent contains peroxidase.
