What Is Blood Testing for Food Allergies?
A food allergy occurs when the body's immune system mistakenly identifies proteins in certain foods as harmful or a threat, triggering an immune response and producing antibodies known as immunoglobulin E (IgE), a key marker of allergic responses. Exposure to these proteins once again can cause reactions that range from mild to severe and may be life-threatening in some cases without prompt care.
A blood test for food allergies can measure the immune system's response to certain foods, such as peanuts, milk, eggs, shellfish, seeds, and tree nuts. It does so by measuring the level of IgE antibodies in your or your child's blood. High levels of these antibodies often point to a food allergy.
When Is Blood Testing for
Food Allergies Recommended?
Blood testing for food allergies can be ideal in several situations. We may recommend it if you or your child has undergone a skin prick test with inconclusive results or if you have a skin condition like eczema that would interfere with skin prick testing. It is also a better option if you can't safely stop taking antihistamines, which is necessary for the success of a skin prick test. Blood testing does not involve direct contact with any allergens.
Blood testing is also used to track IgE levels over time to determine how a treatment is working or whether a child has outgrown an allergy. Keep in mind that when diagnosing food allergies, we always consider the complete picture, including test results, symptoms, and medical history.

What Can You Expect From Blood Testing for Food Allergies?
Having a blood sample drawn is a quick and simple procedure, similar to having routine blood work done. We will collect a small sample of your or your child's blood and send it to a certified lab for analysis. Your results are typically returned to us within a few days.
Elevated levels of specific IgE antibodies indicate sensitization to proteins in certain foods. Our board-certified allergist will review your test results with you, answer your questions, and develop a personalized treatment and management plan to reduce your risk of serious adverse reactions.
Will You Need Additional Testing?
Blood tests provide valuable insights into your immune system's response. However, they are not always definitive. If your results are borderline or if your symptoms don’t align with our test findings, our experienced allergist may recommend a more definitive test known as an oral food challenge (OFC) to confirm the diagnosis.
