In our last “Ask the Doctor” post for Crohn’s and Collitis Month, Jonah Lusis, ND answers a commonly asked question about IgE and IgG food testing.
The allergy test you have with your MD is usually a “skin-scratch” test. This test evaluated whether your body has an IgE (a type of immune system chemical) response to foods. The IgE response is the “immediate” response (e.g., hives, throat constriction) your immune system mounts to foods you are allergic to.
An IgG allergy assessment (such as this one) is a blood test that evaluates foods that trigger an IgG (a second, different immune system chemical) response by your body that also produces inflammation, but is typically delayed, and therefore more difficult to detect (e.g., migraine headaches, eczema).
