The group noted that “positive test results … are to be expected in normal, healthy adults and children,” and that the test “increases the likelihood of false diagnoses … unnecessary dietary restrictions and decreased quality of life.”Īllergy treatments enter a new era - with a focus on stopping reactions before they startĪ spokesperson for EverlyWell stated the company believes “there is a divergence of views regarding IgG tests,” and that the AAAAI does not speak for all health care providers. The company pointed to a handful of small studies that have showed immunoglobulin G helped guide elimination diets - that is, trials of cutting certain foods out of the diet and gauging symptom improvement. And two years later, the Canadian Society of Allergy and Clinical Immunology too released a position statement discouraging the use of the test. In 2010, a subgroup of the American Academy of Allergy, Asthma & Immunology, or AAAAI, endorsed this recommendation. In the report, the group wrote that the test was “irrelevant for the laboratory work-up of food allergy or intolerance and should not be performed in case of food-related complaints.” High levels don’t indicate a problem they simply point to foods a person recently has eaten.įor these reasons, a 2008 European Academy of Allergy and Clinical Immunology task force recommended against testing for a type of immunoglobulin G to evaluate for food intolerance. That’s because immunoglobulin G stems from the body’s normal immune response to exposure to many substances, including food. “In all my years of practice, I have never sent an immunoglobulin G test because they have no ability to predict food sensitivity,” he said. Immunoglobulin G tests “are completely useless and do dramatic harm” because they may compel patients to unnecessarily avoid broad swaths of a healthy diet, Wood said. ![]() Robert Wood, an allergist at Johns Hopkins Children’s Center, whether they have a food sensitivity would never undergo an immunoglobulin G test. (Food allergies, on the other hand, have more serious symptoms and are driven by the immune system validated tests for them do exist.) These symptoms, however, do not involve an immune response. To test or not to testįood sensitivity is an umbrella term that encompasses symptoms that can arise, for example, from difficulty digesting a food, as in lactose intolerance, or susceptibility to the effect of a food, as in caffeine sensitivity. “EverlyWell believes providing this test aligns with relevant third-party research around the test’s usefulness in conjunction with an elimination diet,” the company said in a statement. And allergy experts told STAT that the test is useless at best and could even cause harm if it leads customers to unnecessarily cut nutritious foods from their diet. Yet physician groups have for years advised against using immunoglobulin G tests to evaluate for so-called food sensitivities or intolerances. ![]() ![]() Can a simple diet help change these children’s lives? ![]()
