What This Test Measures

This screening includes antibodies (IgE) to a variety of common allergens, such as pollen, dust mites, pet dander, mold, and certain foods. The test detects if your immune system has developed an allergic response to these substances.

Why It’s Ordered

Your healthcare provider may recommend this test if you experience symptoms like sneezing, itching, rash, or digestive issues that suggest allergies, or if you have a family history of allergies.

Your blood sample is drawn from a vein, typically in your arm. The blood is processed to separate serum, which is then tested for specific IgE antibodies.

The serum is analyzed using a sensitive immunoassay method to detect low levels of IgE antibodies against the allergens listed in the panel.

What to Expect Before the Test

No special preparation is needed. You may eat and drink normally, but avoid alcohol for 24 hours before your blood draw if possible.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.
