Porphyrin fractions panel - Stool
Porphyrin Fract Pnl SFr Stl
Definition
- Determination of porphyrin profile in stool is performed to evaluate porphyria. Total fecal porphyrins are markedly increased especially in active HCP (Hereditary Coproporphyria) and VP (Variegate Porphyria) and to a lesser extent in PCT (Porphyria Cutanea Tarda) and EPP (Erythropoietic Protoporphyria). Porphyrins with 2-4 carboxyl groups generally predominate in feces. As with urine, it is most useful to measure the total amount of porphyrins in a fecal sample. If increased, then the laboratory may determine which porphyrins predominate to identify the presence and nature of the porphyrin defect. A summary of the different porphyria disorders, the genes where mutations occur and the associated symptoms is given in: http://www.porphyria-europe.com/02-for-healthcare/the-porphyrias.asp.
