[Methods of estimation of urinary kallikrein activity (author's transl)].

Catalysing the liberation of kinins, vasodilator and sodium duiretic substances, renal and urinary kallikreins are identical. The urinary excretion of kallikrein may be evaluated by various methods, biological, radioisotopic or enzymatic, giving comparable results. Specific radioimmunoassay of urinary kallikrein in man and the rat have been recently published. Details are given of a rapid and convenient enzyme method.
