What Does This Test Measure?

The test detects specific IgE antibodies in your blood that your immune system produces in response to common food allergens. IgE antibodies are linked to allergic reactions, which can cause symptoms like hives, swelling, difficulty breathing, or digestive issues. This panel screens for IgE levels against multiple allergens in a single test.

Why Might Your Doctor Order This Test?

Your doctor may recommend this test if you have symptoms like skin rashes, digestive problems, or breathing difficulties after eating certain foods. It’s also used to confirm allergies suspected through patient history or skin prick tests, especially in children or adults with suspected food sensitivities.

What to Expect Before the Test

No special preparation is needed for this blood test. You may have a small needle inserted into your arm to draw a blood sample. If you’re on blood-thinning medication, let your doctor know before the test.

What Happens During the Test?

Your blood sample is sent to a lab where it’s analyzed using an immunoassay method to detect IgE antibodies against food allergens. Results are typically available within a few days, though confirmation may take longer depending on the lab.

Frequently asked questions

How Long Does It Take to Get Results?
Results are usually available within 3–7 business days, depending on the lab. Confirmatory testing or follow-up may take longer if additional evaluation is needed.
Can I Eat Normally Before the Test?
Yes, you can eat your regular diet before the test. No special diet or fasting is required.
What If My Test Results Are Positive?
A positive result suggests an IgE-mediated allergy to those foods. Your doctor may recommend avoiding the allergen, working with an allergist for further testing, or managing reactions with medications like epinephrine auto-injectors if needed.
