About Uric Acid
Measurements of Uric Acid are used in the diagnosis and treatment of numerous renal and metabolic disorders, including renal failure, gout, leukemia, psoriasis, starvation or other wasting conditions, and of patients receiving cytotoxic drugs.
Methodology
Uric acid can be determined by direct measurement, by measurement of oxygen consumed or by measurement of hydrogen peroxide produced by the uricase reaction. Several methods utilize coupled enzyme reactions to detect the hydrogen peroxide produced by the uricase reaction. Fossati etal proposed a method which utilized the well established Trinder reaction to measure the hydrogen peroxide produced, and a substituted phenol toenhance sensitivity.
This Uric Acid procedure is a modification of the Fossati method. Uric acid is converted by uricase to allantoin and hydrogen peroxide. Hydrogen peroxide reacts with 4-aminoantipyrine (4-AAP) in the presence of N,N-bis(4-sulfobutyl)-3,5-dimethylaniline, disodium salt (MADB) to produce a chromophore which is read bichromatically at 660/800 nm. The amount of dye formed is proportional to the uric acid concentration in the sample.
