Abstract
The test is based on reducing property of glucose in hot alkaline solution. Proteins are precipitated by tungstic acid and removed by centrifugation. Protein-free filtrate of plasma contains glucose that reduces cupric ions of alkaline CuSO4 to cuprous oxide, which in turn reduces phosphomolybdic acid to molybdenum blue, and color thus produced is measured colorimetrically at 430 nm.
