Uric acid is a metabolic product that results from degradation of purines in the liver. Usually, uric acid is identified from biological fluids, human serum and urine through conventional methods, such as spectroscopy, chromatography, electrochemistry, membrane capillary electrophoresis and spectrophotometric methods, including uricase enzymatic reactions. Importantly, uric acid determination opens the possibility of early intervention in cases of hyperuricemia and preventing the degradation of renal function.
