Uroporphyrins

by

Doctor's Data

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.

Mosaic Diagnostics (formerly Great Plains)

The Porphyrins Profile measures the levels of six porphyrin compounds. Porphyrins are generated as the body builds hemoglobin, the compound that carries oxygen in blood cells. The relative amounts of each porphyrin are altered by certain hereditary diseases and by environmental or nutritional influences.
