title: A simplified procedure for the estimation of arginine in plasma and urine using arginase.
abstract: To ensure reliable arginine estimation, other compounds giving positive results with Chinard's ninhydrin reaction were removed by simple ion-exchange chromatography. Eluted arginine was converted to ornithine by arginase and estimated using Chinard's ninhydrin reaction. Plasma arginine level in adults was in the range 56--98 mumol/l, and urine arginine in the range 0.58--1.77 mg/day.
