title: [Determination of porphyrins in red blood cells. Comparison of two methods (author's transl)].
abstract: Two methods for measuring porphyrin concentrations in red blood cells were compared, one by Piomelli in which porphyrin is extracted from the RBCs and then measured fluorometrically, the other in which the blood-porphyrin content is measured direct with the hematofluorometer ZnP 400. Sample size is the same for both. Results in 59 patients exposed to lead were evaluated: the correlation coefficient between the two tests was 0.99.
