Test ID: UPGDW    
Uroporphyrinogen Decarboxylase (UPG D), Washed Erythrocytes

Useful For Suggests clinical disorders or settings where the test may be helpful

Diagnosis of porphyria cutanea tarda type II and hepatoerythropoietic porphyria

Genetics Test Information Provides information that may help with selection of the correct genetic test or proper submission of the test request

Uroporphyrinogen decarboxylase (UPGD) is deficient in cases of type II porphyria cutanea tarda (PCT). Enzyme analysis is uninformative in sporadic PCT cases.

 

Due to limited stability for this test, the preferred test for analysis of UPGD enzyme is UPGD / Uroporphyrinogen Decarboxylase (UPG D), Whole Blood.
