Think twice before buying an at-home food allergy test kit. These tests might seem like an easy way to find out if you have food allergies. But they can cause more harm than good.
At-home allergy test kits aren’t helpful because:
⚠️ They test the wrong thing. These tests look at IgG antibodies. But IgE antibodies in your immune system are the ones involved in most allergic reactions. At-home tests do not look at these antibodies.
⚠️ Allergy tests only tell part of the story. Doctors look at different factors as a whole to determine if you have a food allergy or intolerance, such as symptoms, medical history, and family history.
⚠️ Inaccurate results from at-home tests can lead you to avoid foods unnecessarily. This may lead to anxiety, family hardship, poor nutrition, and a delay in getting an accurate diagnosis.
If you want to confirm a food allergy or intolerance, spend your money on a visit to see a board-certified allergist who can offer you a proper diagnosis using the right tools.
