IgE Immunoglobulin Allergen-Specific Test (Screening Panel for Multiple Allergens)

What This Test Measures

The test detects levels of IgE antibodies specific to a mix of allergens, including common triggers like pollen, dust mites, pet dander, certain foods, and mold. IgE is a type of antibody that your immune system produces in response to allergens, signaling an allergic reaction may occur.

Why It’s Done

Doctors may order this test if you have symptoms like sneezing, itching, rash, or difficulty breathing that suggest allergies. It helps determine which allergens might be causing your reactions before planning treatment, such as allergy shots or avoiding specific triggers.

Sample Collection and Preparation

A small blood sample is drawn from your arm. The blood is processed to separate the serum (liquid part of blood without clots) for testing. This test is typically done in a lab using an immunoassay method to detect IgE antibodies against the listed allergens.

What to Expect Before or After the Test

No special preparation is needed before the test. You may feel slight discomfort from the needle, but it usually goes away quickly. If you’re on blood-thinning medication, let your doctor know before the test to avoid unusual bleeding.
