Reference Range:

Zinc Protoporphyrin (ZPP), Whole Blood

0-40 µg/dL

Zinc Protoporphyrin (ZPP), to Heme Ratio

0-69 µmol ZPP/mol heme

For occupational exposure to lead, OSHA requires ZPP whole blood concentration to be reported in units of µg/dL. For adults, conversion of ZPP to units of µg/dL assumes a hematocrit of 45%.



Use: Elevated ZPP results are seen in both early and late iron deficiency, the anemia of chronic disease erythropoietic protoporphyria, and chronic lead poisoning. Causes for false elevations include markedly elevated bilirubin or riboflavin, and hemolyzed, clotted or improperly aliquoted specimens.
