Descriptions

Part of porphyrin fractionation testing useful in diagnosing porphyrin cutanea tarda, hereditary coproporphyria, and variegate porphyria. Such patients typically will present with profound elevations of porphyrin analytes (e.g. > 5-fold) during acute episodes. Moderate elevations (e.g. < 3-fold) are more often due to medications or environmental factors. Source: Regenstrief LOINC

Porphyrins are created as byproducts of porphyrinogens. Hereditary enzyme disorders leading to the buildup of porphyrins or porphyrinogens cause porphyrias and affect the heme biosynthetic pathway. Most of these disorders are inherited as autosomal dominant disorders. Increased urine porphyrins are seen with congenital erythropoietic porphyria, acute intermittent porphyria, hereditary coproporphyria, variegate porphyria, and porphyria cutanea tarda.
