Laboratory assay overview
Porphyria is a group of distinct disorders characterized by the abnormal accumulation of porphyrins or porphyrin precursors. Porphyrin fractionation of plasma is useful in diagnosing certain types of porphyrias and excluding porphyrias in patients with chronic renal failure suspected of having a porphyria.
Quest Diagnostics population reference ranges
Quest Diagnostics calculates these statistical intervals for this specific assay and demographic group, not as universal optimal targets.
