[Estimation of the urinary aldosterone (author's transl)].
The urinary aldosterone (ALD) was measured by aldosterone RIA kit and the following results were obtained. (1) We have known that ten percent solution of bovine serum albumin (BSA) instead of free serum LAD is used as the diluent of the urine in aldosterone RIA kit. (2) The upper limits of free ALD, HCl-ALD and beta-glucuronidase ALD in the urine diluted with 10% BSA were 1.6, 9.0 and 9.5 micrograms/dl respectively. (3) The values of urinary conjugated HCl-ALD and beta-glucuronidase ALD were approximately 3.5 times and 4 times as much as that of free ALD respectively. (4) A good correlation was obtained among the results of three methods (HCl-ALD, beta-glucuronidase ALD and free ALD). (5) No difference was found in the values of the urinary ALD in the healthy subjects and the patients with essential hypertension, kidney diseases and acute liver diseases.
