What Does This Test Measure?

The test detects the presence and concentration of IgE antibodies against a mix of common allergens, including dust mites, mold, pet dander, and other environmental triggers. IgE levels indicate how your immune system reacts to these substances.

Why Might You Need This Test?

Your healthcare provider may recommend this test if you have symptoms like sneezing, itching, rashes, or breathing difficulties that suggest allergies. It helps determine which allergens might be causing your reactions.

How Is the Test Performed?

A blood sample is taken from a vein in your arm. The sample is then analyzed in a lab to measure IgE levels specific to the allergens listed in the mix.

What Are the Results Typically Used For?

Results help create a detailed allergy profile. This information can guide treatment plans, such as avoiding specific allergens or determining if allergy medications or immunotherapy might be beneficial.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

This test is critical for diagnosing specific allergies and tailoring treatment strategies. Elevated IgE levels against certain allergens confirm a potential allergic reaction, aiding in managing symptoms and preventing further exposure.

Frequently asked questions

How long does it take to get the results of this test?
Results are typically available within 2 to 3 business days, depending on the lab processing time.
What does a high or low IgE level mean?
A high IgE level against specific allergens suggests an allergic reaction to those substances. A low IgE level does not necessarily mean you lack allergies, but it may indicate a different type of immune response or lack of exposure to those allergens.
Can I take any medications before the test?
Yes, you should inform your healthcare provider about any medications, including antihistamines, you are taking. Some medications may affect the test results, so it’s important to follow your provider’s instructions.
