Both IgE and IgG antibodies show that your body is reacting negatively to something. However,
- IgE antibodies are a sign of a rapid immune response. They can indicate food allergies.
- IgG antibodies are produced more slowly and are typical of food intolerances rather than life-threatening allergies.
- In addition IgA testing may also be offered, which represents another immune pathway, with a growing body of evidence that may increase the sensitivity of the test
