coproporphyrin
Porphyrin in feces
Coproporphyrin is a porphyrin compound found in feces and urine, formed during the biosynthesis of heme.
Elevated levels in urine or stool can indicate certain metabolic disorders, liver disease, or lead poisoning.
The term appears primarily in clinical laboratory contexts: The lab tested for coproporphyrin levels to assess porphyria.
