Abstract
The studies reported above indicate that the angiotensin skin test (A.S.T.) is a simple practical measure which has proved of value in differentiating between normotensive and hypertensive individuals. The duration of the blanching of skin by the test differs significantly in normotensives as compared with hypertensives. The test has served as an index [see figure in the PDF file] of differentiation between an emotionally induced elevation of blood pressure and one which may go on to an established hypertensive state. The A.S.T. is a more reliable test in the diagnosis of the latent, labile, or prehypertensive state than is the cold pressor test. Angiotensin-induced hypertension induces a prolongation of the A.S.T. as compared with control periods.
