Anti-alpha-gal IgG antibodies are present in all people and are not associated with any form of illness. The alpha-gal allergy is a reaction to red meat and all mammalian-derived products that is frequently misdiagnosed and has yet to be fully understood, though much research has been done since it began rising in prevalence over the last ten years. Alpha-gal is a carbohydrate molecule found in most red meat, including beef, pork, and lamb . An alpha-gal allergy is diagnosed the way most allergies are. This proven technique provides the strongest relief from alpha-gal allergy symptoms among all known acupuncture techniques.

Unlike most food allergies, these symptoms typically occur 3-6 hours after eating red meat. The best way to diagnose alpha-gal allergy is with a blood test measuring alpha-gal antibodies. I recommend the panel, but it does cost a bit more. In most cases the diagnosis can be made on a history of delayed allergic reactions to red meat and the blood test for IgE to the oligosaccharide galactose-1,3-galactose (-Gal).

Alpha-gal allergy is a syndrome that was first described in 2009 as a delayed anaphylaxis to red meat, specifically an excessive IgE antibody response to an oligosaccharide epitope, galactose This test is not available at LabCorp Note: Result turn around times are an estimate and are not guaranteed. Introduction: Alpha-gal syndrome is a potentially severe food allergy caused by the presence of alpha-gal-specific IgE. It was first discovered in 2009. Alpha-gal, a sugar carbohydrate found in beef, lamb, and pork is thought to be associated with a rare meat allergy, which produces a hive-like rash; and, in some people, a dangerous anaphylactic reaction roughly 4 hours after consuming the meat. First described in 2009, the alpha-gal allergy (red meat or mammalian allergy) is a novel form of IgE-mediated anaphylaxis; unlike most anaphylaxis, this reaction is delayed. 2018/04/17.

An alpha-gal allergy is diagnosed the way most allergies are. A question in the Ask the Expert archives addresses this issue (4). [15] [27] Determination of specific IgE to alpha-gal testing is commercially available, as well as IgE testing to specific red meats. -Gal-associated meat allergy is a recently described syndrome in which individuals who have been bitten by ticks of the Ixodidae family become sensitized to the carbohydrate determinant galactose--1,3-galactose (-Gal). Your doctor should be able to determine if you have AGS based upon your clinical symptoms and a positive blood test: immunoglobulin E (IgE) to the oligosaccharide glactose-alpha-1,3 galactose (alpha-gal.) IgE to Alpha-Gal is the likely cause of anaphylactic reactions in individuals who develop hypersensitivities to beef, pork and/or lamb Since the reaction to eating mammal meat is delayed by several hours, the proper diagnosis is often missed or misdiagnosed. An allergy skin test result that is interpreted by the ordering provider as consistent with alpha-gal allergy based on sensitivity to one or more mammalian meats (e.g., pork, beef, lamb) or other mammalian-derived products. Since this reaction is delayed, it takes longer for symptoms to develop than a regular food allergy, about 3 to 4 hours. In the United States, the condition most often begins. Ingredients that may contain alpha-gal include, but are not limited to: Gelatin. The Alpha-Gal Panel includes specific meat allergen tests as well as a test for galactose-alpha-1,3-galactose (alpha-gal). Why should you use SAAT treatment for Alpha-Gal: There is The galactose-alpha-1, 3-galactose (alpha-gal) is a sugar molecule (carbohydrate) that is found in every mammal EXCEPT humans, apes, and old world monkeys. Unlike most food allergies, alpha-gal may not cause a reaction until hours after the meat has been consumed. With alpha-Gal allergen component blood testing, providers have access to a quantitative and reliable measure of specific IgE sensitization that can help aid in this especially challenging diagnosis. Similar to other allergies, skin tests through pricking the skin with a small amount of alpha-gal can identify reactions to the sugar in allergic patients. If your doctor is unable to do this test, they may do a test in which they expose a small part of your skin to a tiny amount of alpha-gal to check for a reaction. What should I do if I have AGS?

Alpha gal allergy testing. This test measures the amount of IgE anti-alpha-gal antibodies in the blood. In geographic areas where tick bites are common, AGS is likely under-recognized and under-diagnosed. Acquired red meat allergy is an allergy to certain types of meat caused by the bite of a lone star tick. 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). Results: A total of 1112 adult patients underwent alpha-gal IgE testing and 359 (32.3%) were positive. Glycerin.

C. Case classification CONFIRMED A case that meets clinical criteria and confirmatory laboratory evidence PROBABLE Alpha-gal allergy is a condition in which the immune system overreacts to certain compounds in red meat. dr. commins talks about the symptoms of a reaction, how one can be tested for the allergy, and changes in diet recommended for patients who have alpha-gal. Southern Medical Journal. Other pertinent history includes recent outdoor activity, exposure to ticks, and any known or suspected reaction after consuming mammalian meats. Additional tests used in the evaluation of alpha-gal syndrome may include: Blood test. An investigational blood test, IgE against alpha-gal itself, may also aid in the diagnosis. Alpha-Gal Allergy as a Cause of Intestinal Symptoms in a Gastroenterology Community Practice. There is commercial testing available for IgE to alpha-gal, but Dr. Cummins feels comfortable with administering vaccine in individuals who can tolerate dairy (4). One is only the alpha-gal IgE level, while the other (the panel) is the IgE number as well as the breakdown for beef, pork, lamb. Alpha-gal is a carbohydrate found in mammals, except for humans and the great apes. Avoid wooded bushy areas with long grass where ticks are usually found. Alpha-gal allergy cases have now been reported throughout the world. The alpha-gal injection triggers a cascading immune reaction of antibodies called Immunoglobulin E (IgE). [28]

Researchers now believe that some people who have frequent, unexplained anaphylactic reactions and who test negative for other food allergies may be affected by alpha-gal syndrome. Magnesium stearate. In 2002 it was first discovered by Dr. Thomas Platts-Mills, also at the University of Virginia, that The most common symptom is a red, blotchy, itchy rash, known as hives. 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). your doctor will do a Testing for an Alpha-gal Allergy Alpha-gal allergy is typically diagnosed through a combination of: Medical history Physical exam Blood tests The blood tests help to find alpha-gal antibodies that are created by the immune system. Alpha galactose, the Alpha-gal allergy has commonly been referred to as the red meat allergy, but doctors at the Vanderbilt Asthma, Sinus and Allergy Program (ASAP) helped . It is also present in tick saliva. Interestingly, the allergist who discovered alpha gal is Dr. Tom Platts-Mills at UVA Charlottesville med school.
