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 (eg, gelatin)
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.
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.
Other meat allergen IgE antibody tests may be considered in addition to galactose-alpha-1,3-galactose IgE antibody testing in cases of suspected red meat allergy.
