Alpha-gal syndrome is a potentially serious allergic condition triggered by the bite of the Lone Star tick. It causes the immune system to produce IgE antibodies against galactose-alpha-1,3-galactose, a sugar molecule found in most mammalian meat and products. Reactions typically occur 3 to 6 hours after eating red meat, pork, or dairy, making it difficult to identify without testing. Cases are rising rapidly across the southeastern and eastern United States.
Allergy-specific IgE testing helps identify what your immune system is reacting to so you can avoid triggers, plan immunotherapy, and reduce symptoms.
Anyone with recurrent allergy symptoms (rash, sneezing, GI distress, breathing difficulty) who wants to identify specific triggers without elimination diets or skin testing.
