Abstract
An improved azobilirubin determination procedure utilizes a stable, dry lyophilized reagent. Dissolving the dry reagent in dilute hydrochloric acid produces a diazo reagent solution which is stable for several days. Cysteine hydrochloride may be added to the assay mixture to destroy excess diazo reagent, stabilize the final color, and remove interfering metal ions.
