| ||Zinc Protoporphyrin (ZPP), Whole Blood
| ||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%.
Elevated ZPP results are seen in early and late iron deficiency, the anemia of chronic disease, chronic lead poisoning, and erythropoietic protoporphyria. Elevated bilirubin or riboflavin and hemolyzed, clotted, or improperly aliquoted specimens may falsely increase the ZPP concentration.
