[The value of stimulation of the renin-angiotensin-aldosterone system as a screening test for hypertension (author's transl)].

Renin activity, angiotensin-II concentration and venous aldosterone concentration were measured in 20 healthy subjects and 18 hypertensives before and after stimulation of the renin-angiotensin-aldosterone system. The test did not distinguish between the two groups: in the individual case there was no relationship between renin-activity, angiotensin-II concentration and aldosterone concentration in peripheral venous blood. Stimulation of the system without sodium balance is not a reliable screening test for hypertension.
