Food Allergen-Specific IgE Antibody Panel (17 Allergens), Serum
A blood test that measures IgE antibodies to a panel of 17 foods, helping identify foods that may trigger an allergic reaction.
["Results can show which foods your immune system has sensitized to, but your symptoms and medical history are also needed to determine whether you have a food allergy."]

What is this test?
This test measures food-specific IgE antibodies in your blood. It evaluates reactions to a group of 17 food allergens, although the exact foods included can vary by laboratory.
Why might I need this test?
Your clinician may order this panel if you have symptoms such as hives, swelling, abdominal pain, vomiting, wheezing, or reactions after eating certain foods. It may also be used to track suspected food allergies or evaluate reactions before allergy testing.
How is the test performed?
A blood sample is collected and tested in a laboratory using an immunoassay to detect IgE antibodies to the foods on the panel. The report usually lists each food separately with a qualitative or numerical result.
How do I prepare for the test?
No special food restrictions are usually required. Tell your clinician about any medicines you take, especially antihistamines, because some allergy medicines and certain other treatments may affect test results; do not stop prescribed medicine without guidance.
Reference range
Adult: 10-40 U/LN/A
No special preparation required. Avoid fatty meals before the test if possible.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
A positive result indicates immune sensitization to the tested food and may support a suspected food allergy, but it does not by itself prove that eating the food will cause a reaction. Results must be interpreted with your symptoms, exposure history, and sometimes additional allergy testing. A negative result lowers the likelihood of IgE-mediated allergy to that food but does not completely exclude it, and some reactions may involve non-IgE mechanisms.
Short name
Food allergen IgE panel
Frequently asked questions
Does a positive result mean I am allergic to that food?
