Establishing a differential diagnosis of erythropoietic protoporphyria, X-linked dominant protoporphyria, iron-deficiency anemia, and chronic lead intoxication

Testing begins with total RBC porphyrins. If the result is <80 mcg/dL, it is normal and testing is complete. If the total RBC porphyrin value is > or =80 mcg/dL, the protoporphyrin fractionation assay will be performed at an additional charge to identify the porphyrin involved. The protoporphyrin fractionation yields free protoporphyrin and zinc-complexed protoporphyrin.
