title: A two-stage enzymatic method for determination of uric acid and hypoxanthine/xanthine.
abstract: A method is described by which plasma or serum concentrations of uric acid and hypoxanthine/xanthine may be determined in a two-step sequential method. The principle of the method is that hydrogen peroxide, liberated by the action of uricase and xanthine oxidase on their substrates, is coupled to the production of a coloured product.
