Hemoglobin and the heme released by hemoglobin degradation are converted to porphyrins. These porphyrins are quantified by fluorescence measurement after extraction of any interfering fluorescing substances.(Schwartz S, Dahl J, Ellefson M, Ahlquist D: The "HemoQuant" test: a specific and quantitative determination of heme [hemoglobin] in feces and other materials. Clin Chem 1983;29:2061-2067)
