Alpha-gal syndrome describes a spectrum of symptoms resulting from an IgE-mediated allergy to the disaccharide α-gal. The specific IgE immunoassay that confirms a diagnosis was first introduced in 2012.1 Thus, alpha-gal syndrome is a relatively new disease and researchers are investigating its exact mechanism of development. Alpha-gal disaccharide is a blood group substance of non-primate mammals found on glycolipids and glycoproteins in the meat of beef, pork, and lamb, as well as goat, rabbit, squirrel, and horse.2 A patient with IgE-mediated α-gal allergy will develop an allergic response after eating meat from these animals (red meat). There is a globally reported association between tick bites and IgE antibodies to α-gal.3 In the United States, Amblyomma americanum is identified as the culpable tick species. The range of A americanum, also known as the Lone Star tick, spans the Southeastern region of the United States, the same area from which most cases of allergic reactions to red meat are reported.
