What This Test Measures

The test evaluates levels of IgE antibodies against a mix of common food allergens, including but not limited to dairy, eggs, peanuts, tree nuts, wheat, soy, fish, and shellfish. IgE antibodies are part of your immune system’s defense mechanism that can trigger allergic reactions when exposed to these foods.

How the Test Works

Blood is drawn and processed to separate serum, where IgE antibodies specific to the listed allergens are detected using immunoassay methods. This helps determine if your immune system is sensitized to these foods.

Why It’s Done

Doctors may order this test if you have symptoms like hives, swelling, difficulty breathing, or digestive issues after eating certain foods, or if you suspect a food allergy based on medical history.

What to Expect Before the Test

No special preparation is needed. You may have a slight bruise or discomfort at the injection site, but blood drawing is quick and usually painless.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

This test helps confirm suspected food allergies by identifying IgE antibodies, which can guide dietary changes or further testing if needed. It’s particularly useful for diagnosing allergies that cause immediate reactions.
