Abstract:

A comparison of the Hoesch and the Watson-Schwartz tests shows that the latter, although slightly more complicated, generally yields more concise results and is superior in sensitivity and specificity for porphobilinogen. The recommendation of the Hoesch test for use as a "bedside screening" method seems unrealistic. Before the diagnosis of an "inducible" porphyria is made, a positive Hoesch test requires that indoles, indoleacetic acid, methyldopa, end-stage alcoholic malnutrition, and phenazopyridine HCl be excluded, to avoid misinterpretation.
