RE: Research sites that do not recommend igg tests21 Aug 2024 11:02
Immunoglobulin G (IgG) blood tests are not recommended for diagnosing food allergies, intolerances, or sensitivities. The tests claim that removing foods with high levels of IgG from your diet can improve health and address symptoms, but research doesn't support this. In fact, the presence of IgG antibodies may indicate exposure to a food, or possibly tolerance, but not an allergy.
Some reasons why IgG tests are considered unreliable include:
Lack of evidence
There's no evidence to support making changes based on IgG test results. For example, the restrictions suggested by the tests may lead people to avoid healthy foods or include foods that could be harmful to them.
Outdated studies
Scientific studies that support the use of IgG tests are often out of date, in non-reputable journals, or haven't used the IgG test in question.
Not a recognized diagnostic tool
Food-specific IgG testing is not a recognized diagnostic tool for food allergies
