Abstract
The chemical laboratory measures used in the diagnosis of pheochromocytoma have been evaluated. Bio-assay, fluorometric, and spectrophotometric methods were used. Urinary VMA and catechol amine values found for normal and hypertensive groups compared well with those reported by other investigators. The quantitative measurement of urinary VMA by means of a proposed ethyl acetate extraction proved quite reliable.Keywords
