Test ID: APGAL
Galactose-Alpha-1,3-Galactose (Alpha-Gal) Mammalian Meat Allergy Profile, Serum
Useful For 
Suggests clinical disorders or settings where the test may be helpful
As an aid in diagnosis of an IgE mediated hypersensitivity allergy to non-primate mammalian red meat or meat-derived products, such as beef, pork, venison, and meat-derived products such as gelatin via allergen profile testing
This test is not useful in patients previously treated with immunotherapy to determine if residual clinical sensitivity exists.
This test is not useful for patients in whom the medical management does not depend upon identification of allergen specificity.
Highlights
The presence of IgE antibodies against galactose-alpha-1,3-galactose (alpha-gal) is associated with red meat allergy.
Individuals with IgE antibodies against alpha-gal might develop anaphylactic reactions to the drug cetuximab.
