Résumé : The quantification of total urinary porphyrins based on spectrophotometry or spectrofluorimetry is a key screening test in cutaneous or mixed porphyria, performed before the quantitative fractionation of porphyrin isomers by chromatography. The aim of the present study was to determine the best threshold value for a spectrophotometric screening test and to estimate its diagnostic performances.
