Allergy Screen Blood Test

Allergy Screening

An Allergy Screen, also known as an IgE Blood Test or Comprehensive Allergy Test, is a diagnostic procedure used to identify specific allergens that may be causing an individual's allergic reactions. This test is crucial in pinpointing the exact cause of allergy symptoms, enabling more targeted and effective treatment.

What does the test look for?

The Allergy Screen primarily measures the level of Immunoglobulin E (IgE) antibodies in the blood. These antibodies are produced by the immune system in response to allergens. The test typically covers common allergens such as dust mites, pet dander, mould, pollen, and certain foods. However, the specific allergens tested for may vary slightly between providers.

How can this test help you?

Understanding the specific allergens that trigger your symptoms can guide effective treatment and lifestyle changes. By avoiding identified allergens, you can reduce the frequency and severity of allergic reactions. Furthermore, your healthcare provider can tailor your treatment plan based on the results, which may include medications, immunotherapy, or dietary changes.
