    Abstract:
    The AA. have compared five different methods for measuring urinary porphyrins (Bio-Rad porphyrins, Porphyrin-T Sibar, Reinkingh-Van Kampen, Schwartz and coll., Fischer-Ham). Based on the results obtained, for total porphyrins the best method appeared to be the Porphyrin-T Sibar test, while for the separate evaluation of uro- and coproporphyrins the most suitable method proved to be the one proposed by Reinkingh-Van Kampen. The investigations has also allowed the AA. to conclude that spectrophotometric reading can replace the fluorimetric one, without affecting the accuracy of results.
