Test Overview
Immunoassay
The Galactose-alpha-1,3-galactose (Alpha-Gal) IgE test more specifically defines the etiology of allergic responses to meat allergens in patients with a delayed onset of symptoms (3 to 6 hours after meal). IgE to Alpha-Gal is the likely cause of anaphylactic reactions in individuals who develop hypersensitivities to beef, pork and/or lamb as adults.
