Are allergy tests reliable?

Allergy test reliability, especially concerning IgG antibody tests, is a debated topic. According to Dr. Stephen Cabral on the Mind Pump Podcast, IgG tests measure delayed immune responses to foods. This method is widely used, including by major hospitals, but it's essential to distinguish between different types of antibodies: IgE (immediate allergies) and IgG (delayed food sensitivities). The controversy around these tests stems from the fact that they often show sensitivity to many foods people commonly eat, which could be due to gut permeability issues rather than true allergies 1.

In summary, while IgG tests can provide valuable insights, their results need to be interpreted carefully, considering the individual's overall gut health and the difference between true allergies and food sensitivities.
