How do I prepare to take the indoor and outdoor allergy test?

Unlike a skin prick test, there are no medication or supplement restrictions prior to collecting your blood sample. Antihistamines are intended to stop histamine, not IgE antibodies. Histamine is a chemical released upon subsequent exposure to an allergen. We are measuring IgE antibodies on this test (not histamine), so antihistamines will not affect your test results.

Although glucocorticoids, also known as steroid medications, may decrease IgG levels (the antibody measured in our Food Sensitivity Test), studies suggest they can also increase IgE levels (the antibody measured in this test). Testing can be performed, but the results should be interpreted in the appropriate clinical context by your healthcare provider. You should not discontinue any of your current medications or supplements without discussing this with your healthcare provider.

If you were previously diagnosed with indoor or outdoor allergies and are on immunotherapy or allergy shots to reduce IgE reactivity, that treatment is intended to lower your IgE levels over time by “training your body” to become less allergic. We would not recommend stopping treatment to perform this test without consulting with your healthcare provider. In fact, this test may be useful in seeing if your IgE reactivity is decreasing with your treatment plan.
