Clinical Info

Aids in the diagnosis of alpha-Gal associated meat allergy in which individuals who have been bitten by ticks of the Ixodidae family become sensitized to the carbohydrate determinant galactose-α-1,3-galactose (α-Gal).
A distinctive feature of this allergy is the delayed onset of symptoms, which occurs 2-6 hours after eating meat. The delayed symptom onset is thought to reflect the appearance of glycolipid α-Gal moieties, which are believed to be involved in the allergic reaction, in the bloodstream.
