RE: List of bodies that recommend not using IGG tests1 Jan 2024 13:47
"Take for instance, the IgG tests. This test involves exposing a sample of your blood to different foods and measuring the resulting antibody (IgG). However, most of us will develop IgG antibodies to food during our lifetime, despite not getting symptoms. This is because IgG is an indicator of repeated exposure, not a food intolerance.’
Colucci concurs. 'Whenever we eat any food, our body produces a small level of IgG antibodies to help us digest that particular food. Therefore, these tests often come back with a whole list of foods the patient is intolerant to, but in reality these are the foods they have most recently eaten, or the foods they eat the most of.'
