Monitoring treatment of patients with porphyria cutanea tarda
Plasma specimens from patients with active porphyria cutanea tarda, congenital erythropoietic porphyria, and erythropoietic protoporphyria may exhibit increased plasma porphyrin levels. However, a definitive diagnosis cannot be made by plasma analysis alone.
Plasma porphyrins are most appropriate for monitoring patients being treated for porphyria cutanea tarda.
Analysis of plasma porphyrins is suitable for individuals with bullous dermatosis who are in chronic renal failure and unable to provide a urine specimen.
