LaboratoryGalactose-alpha-1,3-galactose (Alpha-Gal) IgE Ab [Units/volume] in Serum
Definition
Galactose-alpha-1,3-galactose (Alpha-Gal) IgE test may be used to help diagnose allergic responses to meat allergens in patients with a delayed onset of symptoms, such as anaphylactic reactions, 3 to 6 hours after eating beef, pork and/or lamb. IgE to Alpha-Gal is the likely cause of anaphylactic reactions. Results are calibrated against total IgE standards from WHO Reference 75/502 to generate results in kilounits (kU) of IgE.
