Alpha-gal is 2 galactoses.

The alpha-gal injection triggers a cascading immune reaction of antibodies called Immunoglobulin E (IgE). Unlike most food allergies, alpha-gal may not cause a reaction until hours after the meat has been consumed. Our reference lab may need additional time due to weather, holidays, confirmation/repeat testing, or equipment maintenance. The aim of this study is to describe our series of 13 patients.

Introduction: Alpha-gal syndrome is a potentially severe food allergy caused by the presence of alpha-gal-specific IgE. A blood test for galactose-alpha-1,3-galactose (alpha-gal) specific IgE (sIgE) is the main test that healthcare providers use to help them diagnose alpha-gal syndrome ( 1, 2). Some patients may dr. scott commins is an associate professor of This specific allergy is related to a carbohydrate called alpha-gal and is best diagnosed with a blood test.

When a person with the alpha-gal antibody eats mammalian meat, the meat triggers the release of histamine, a compound found in the body that causes allergic symptoms like hives, itching and even anaphylaxis (a reaction that leads to sudden weakness, swelling of the throat, lips and tongue, difficult breathing and/or unconsciousness). Alpha-gal is a carbohydrate found in mammals, except for humans and the great apes.
