Porphyrin complexes of zinc have been known since the 1930s. In 1974 ZPP was identified as a major non-heme porphyrin formed in red cells as the result of lead poisoning or iron deficiency., It was already known at this time that non-heme protoporphyrin IX levels were elevated in these conditions, but prior investigators had used acidic extraction methods in their assays that converted ZPP to unbound Protoporphyrin IX. WebThe free erythrocyte protoporphyrin (FEP) test measures the concentration of nonheme protoporphyrin in red blood cells. Protoporphyrin comprises the predominant porphyrin …
