Abstract
A rapid and simple chemical technic for screening hypertensive subjects for the presence of a pheochromocytoma is described. The procedure involves the semiquantitative estimation of urinary 3-methoxy, 4-hydroxymandelic acid (VMA). This test differentiates between normal subjects or patients with primary hypertension and patients with pheochromocytoma. A negative result requires no further study whereas a positive one necessitates confirmation by Chromatographic determination of VMA.
