Compensation by zinc chelation for fluorescent background in determining coproporphyrin and uroporphyrin in urine.


An improved method for separation and fluorescent analysis of coproporphyrin and uroporphyrin in urine was presented by Sobel, Cano, and Thiers [Clin. Chem. 20, 1397 (1974)]. Accurate determination of porphyrin concentrations by this method is impeded by the fluorescent background in urine samples, which varies from one specimen to another. By use of a… (More)
