Measurement of urine porphyrins and porphyrinogens
Abstract
A simple and rapid method for quantitative analysis of urine porphyrins is described. After acidification of urine to 1 n with HCl, the first derivative of the absorption spectrum is recorded in the region of the Soret band maximum. Nonspecific interference is not significant, and the point of intersection of the derivative of the Soret band maximum with the baseline provides an estimate of the ratio of uro- to coproporphyrins. Using this …
