Tests and diagnosisBy Mayo Clinic Staff
- Urine test. If you have a form of acute porphyria, a urine test may reveal elevated levels of two substances: porphobilinogen (por-foe-bih-LIN-uh-jen) and delta-aminolevulinic (uh-me-no-lev-yoo-LIN-ik) acids, as well as other porphyrins.
- Blood test. If you have a form of cutaneous porphyria, a blood test may show an elevation in the level of porphyrins in your blood plasma.
- Stool sample test. Analysis of a stool sample may reveal elevated levels of some porphyrins that may not be detected in urine samples. This test may help your doctor determine your specific type of porphyria.
