Unit Code 88924:
Aminolevulinic Acid Dehydratase (ALA-D), Erythrocytes
Useful For 
Suggests clinical disorders or settings where the test may be helpful
Confirmation of a diagnosis of aminolevulinic acid dehydratase
deficiency porphyria (ADP)
Genetics Test Information Provides information that may help with selection of the correct test or proper submission of the test request
ALA-D activity is inhibited in other situations including hereditary
tyrosinemia type 1, lead intoxication, and exposure to styrene,
trichloroethylene, or bromobenzene. These causes should be
ruled out when considering a diagnosis of ALA-D deficiency
porphyria (ADP).
