Establishing a biochemical diagnosis of erythropoietic protoporphyria and X-linked dominant protoporphyria
Test ID | Reporting Name | Available Separately | Always Performed |
---|---|---|---|
PPFE | Protoporphyrins, Fractionation, WB | Yes | No |
This test is recommended for screening patients for possible erythropoietic protoporphyria and X-linked dominant protoporphyria. In addition, it can be used for evaluation of iron-deficiency anemia and chronic lead intoxication. Testing begins with total erythrocyte porphyrins. If the result is below 80 mcg/dL, it is normal and testing is complete.
If the total erythrocyte porphyrin value is 80 mcg/dL or above, the protoporphyrin fractionation assay will automatically be performed at an additional charge. The fractionation test results include noncomplexed (free) protoporphyrin and zinc-complexed protoporphyrin.
