FDA approves First blood Test to Identify fatal allergy to Red Meat

According to the American Academy of Asthma, Allergy and Immunology, an allergy to alpha-Gal can cause patients to have a severe and potentially life-threatening reaction to galactose-alpha-1, 3-galactose that is found in most mammalian (red) meat. Unlike other food allergies, reactions from eating red meat may be delayed, occurring three to eight hours after eating. Symptoms range from hives and itching, to abdominal pain, nausea or vomiting. In severe cases the allergy can cause anaphylaxis which can be potentially fatal. The condition can appear in patients who have tolerated meat for many years, with researchers believing that sensitization to alpha-Gal may be the result of a bite from the lone star tick (Amblyomma americanum).

"Alpha-gal is dramatically different from other forms of food allergy," said Thomas Platts-Mills, MD, professor of medicine and microbiology at the University of Virginia School of Medicine and a leading researcher on the topic. "Previously healthy adults can suddenly develop potentially life-threatening reactions to red meats such as beef, pork and lamb. The delayed nature of the reactions adds to the difficulty that clinicians and patients have in identifying the cause of the symptoms. This unique set of circumstances makes an accurate diagnosis critical for managing this disease."

The ImmunoCAP Specific IgE Stinging Insect Allergen Component tests were recently cleared by the Food & Drug Administration to help improve the diagnosis of bee and wasp allergies. ImmunoCAP Specific IgE blood tests, which are available in most major U.S. laboratories, can be ordered for patients of any age regardless of skin condition, current medication, disease activity or pregnancy status.
