Description
A peanut allergy IgE blood test measures the amount of immunoglobulin E (IgE) antibodies in your blood that are specific to peanuts. This test can help determine if you have a peanut allergy, and identify the specific proteins in peanuts that cause your reaction.
Purpose Diagnose peanut allergies, Identify specific allergens that cause symptoms, Confirm sensitization before immunotherapy, and Evaluate patients with suspected peanut cross-reactivity.
How it works
- Your immune system produces IgE antibodies when it perceives a foreign substance, like a peanut, as a threat
- The test measures the amount of IgE antibodies in your blood
Fasting not required.
