This profile measures urine porphyrins, which are associated with high-level exposure to mercury, arsenic, lead, and some chemicals and drugs. It reports precoproporphyrins separately and per unit of uroporphyrin to increase detection even when heme biosynthesis is low. This test uses a first-morning void urine collection. It can also be ordered as a 24-hour collection.
