Preferred screening test during symptomatic periods for acute intermittent porphyria, hereditary coproporphyria, and variegate porphyria (additional confirmatory testing is required to establish a diagnosis)
Preferred screening test to begin assessment for congenital erythropoietic porphyria and porphyria cutanea tarda (additional confirmatory testing is required to establish a diagnosis)
Genetics Test Information Provides information that may help with selection of the correct test or proper submission of the test request
