Test ID: PTP
Porphyrins, Total, Plasma
Useful For 
Suggests clinical disorders or settings where the test may be helpful
Monitoring treatment of patients with porphyria cutanea tarda
Genetics Test Information Provides information that may help with selection of the correct genetic test or proper submission of the test request
Plasma specimens from patients with active porphyria cutanea tarda, congenital erythropoietic porphyria, and erythropoietic protoporphyria may exhibit increased plasma porphyrin levels. However, a definitive diagnosis cannot be made by plasma analysis alone.
Highlights
Plasma porphyrins are most appropriate for monitoring patients being treated for porphyria cutanea tarda.
Analysis of plasma porphyrins is suitable for individuals with bullous dermatosis who are in chronic renal failure and unable to provide a urine specimen.
Reflex Tests Lists tests that may or may not be performed, at an additional charge, depending on the result and interpretation of the initial tests.

Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.
If total porphyrins are above 1.0 mcg/dL, then porphyrin fractionation will be performed at an additional charge.
