The Purpose of an IgE Test

Chronic allergies aren’t just uncomfortable, with persistent coughing, watery eyes, and a stuffed-up nose. In certain cases, they can also be dangerous, with your body reacting so severely that you could go into anaphylactic shock. To help end your suffering or prevent a life-threatening incident, you can get an immunoglobulin E test.

What Does the IgE Lab Test Measure?

Your body produces the immunoglobulin E antibody in response to allergen exposure, whether that’s pollen, animal dander, food, or mold. IgE can be measured by testing your skin or blood. The latter is advised if you have sensitive skin, can’t stop taking allergy medication, or need comprehensive allergy testing. The IgE test measures the levels of this antibody in your blood.

Who Should Take an Immunoglobulin E Blood Test?

If you need medication to stifle symptoms such as wheezing, hives, congestion, or other common signs of allergies, you should take the IgE blood test.

IgE Lab Test Preparation

You don’t have to take any special precautions before the IgE blood draw; in fact, you may be able to continue taking your allergy medication if needed. Talk to your physician or the lab for further instructions.

Immunoglobulin E Test Results

Different tests have different normal ranges. If your test report states that you have higher levels of IgE in your blood, that can be a sign you have an allergy, although this test doesn’t pinpoint which allergen is your trigger. If necessary, you can get further allergy testing, including tests for specific foods and environmental allergens.
