FAQ
Why should I get tested?
If you are experiencing frequent use of your rescue inhaler, wake up at night due to asthma symptoms, take oral steroids like prednisone, and/or have asthma attacks that have required emergency care, then your asthma may be severe or uncontrolled. This, along with a high e-number, can indicate eosinophilic asthma. A blood test can help you determine if further evaluation of your asthma is necessary. Speaking with your primary care provider or asthma specialist about the test results can help identify additional treatment options to help control your asthma.
What qualifies me as eligible for this test?
If you have severe, uncontrolled asthma, you are qualified to receive this test. You can determine your eligibility by completing the pre-test questionnaire that appears when you begin the order process.
This test is intended for adults age 18 and older who have been diagnosed with asthma by a physician.
If you are pregnant, please see your primary care physician, as there may be additional considerations. Further evaluation is often needed to maintain the safety of your unborn child.

What is the blood testing process?
You will be tested at a Quest Diagnostics patient service center. The test is a simple blood draw where an experienced health professional will take some blood from a vein in your arm.
What will my results tell me?
This test is called a complete blood count, or CBC. The test helps screen for a wide range of conditions to give an overall view of an individual’s health. A CBC looks at three types of cells in your blood: white blood cells, red blood cells, and platelets.
Your results will show if you have eosinophils present in your blood. This will help determine whether eosinophils play a role in making your asthma worse.
Discussing your results with a doctor can help determine if you are on the right medications or if you may need further assessment for better control of your asthma.

An asthma specialist can evaluate your e-number and help identify if eosinophils are affecting your asthma.
Please note, the lab report provided by Quest Diagnostics uses a normal range of 15-500 to reflect a general population.
