Porphobilinogen Quantitative Random Urine Test
The Porphobilinogen Quantitative Random Urine Test measures levels of porphobilinogen, a heme precursor that accumulates in acute porphyrias. Elevated results may indicate disorders such as acute intermittent porphyria, presenting with abdominal pain, neurological changes, or dark urine. This test provides insights into heme biosynthesis, helping evaluate metabolic and hereditary conditions linked to porphyrin pathway dysfunction.
