About this test
Alpha-galactosidase is an enzyme, and this test measures its activity level in a frozen serum sample using a fluorometric method. Quest describes it as the preferred screening test for Fabry disease and notes it is used in evaluating Fabry disease in males.
Quest also notes that this test is not useful for evaluating a meat or meat-derived product allergy, a distinction worth knowing because alpha-galactosidase is sometimes confused with alpha-gal, the carbohydrate associated with that kind of allergy.
