Preferred screening test for congenital erythropoietic porphyria and porphyria cutanea tarda and during symptomatic periods for acute intermittent porphyria, hereditary coproporphyria, and variegate porphyria when specimen transport will be longer than 72 hours (if the specimen will be received at Mayo Medical Laboratories within 72 hours of collection, PQNRU / Porphyrins, Quantitative, Random, Urine is recommended)
Preferred test during symptomatic periods for acute intermittent porphyria (AIP), hereditary coproporphyria (HCP), and variegate porphyria (VP) when specimen transport will be longer than 72 hours. If the specimen will be received at Mayo Medical Laboratories within 72 hours of collection, PQNRU / Porphyrins, Quantitative, Random, Urine is recommended.
Testing includes porphobilinogen, which is useful in the evaluation of the acute porphyrias.
Preferred test to begin assessment for congenital erythropoietic porphyria (CEP) and porphyria cutanea tarda (PCT).
The following algorithms are available in Special Instructions:
-Porphyria (Acute) Testing Algorithm
-Porphyria (Cutaneous) Testing Algorithm
Includes quantitation of coproporphyrins, uroporphyrins, and intermediate porphyrins (heptacarboxyl, hexacarboxyl, and pentacarboxyl).
Includes liquid chromatography-tandem mass spectrometry (LC-MS/MS) determination of porphobilinogen.
