diazo reaction

di·a·zo re·ac·tion

the reaction of diazotized sulfanilic acid with bilirubin to form azobilirubin, which forms the basis of quantitating the amount of bilirubin in biologic fluids. See: van den Bergh test.
Synonym(s): Ehrlich diazo reaction

diazo reaction

(dī-ăz′ō)
A deep red color in urine, produced by the action of p-diazobenzene-sulfonic acid and ammonia on aromatic substances found in the urine in certain conditions.
