Fractionated urine porphyrin
This test is done to measure and differentiate various porphyrins excreted in urine. Porphyrins are compounds involved in heme production. Abnormal patterns help diagnose different types of porphyria, a group of rare metabolic disorders, and can also indicate liver dysfunction or toxin exposure affecting heme synthesis.
- If porphyria is suspected.
- If there are symptoms like abdominal pain, neuropathy, or photosensitivity.
- If unexplained neurological or skin symptoms are present.
- If a healthcare provider is evaluating heme metabolism disorders.
