Porphyrins Fractionated Quantitative Random Urine Test
The Porphyrins Fractionated Quantitative Random Urine Test measures porphyrin levels and patterns to evaluate disorders of heme biosynthesis. Abnormal results may indicate porphyrias, liver disease, or toxic exposures affecting red blood cell production. By fractionating uroporphyrin, coproporphyrin, and other intermediates, this test supports investigation of metabolic dysfunction, unexplained neurological issues, or photosensitivity.
