What This Test Measures

The test looks for IgE antibodies—your body’s natural defense that may react to airborne allergens like pollen, pet fur, or dust. Elevated levels suggest a heightened sensitivity to these substances.

Why It’s Done

Your doctor may recommend this test if you experience persistent symptoms like coughing, wheezing, or skin rashes that don’t improve with usual treatments, or if you live in an area with known allergen exposure.

How It Works

A small blood sample is taken and analyzed to detect IgE antibodies specific to common indoor allergens. Results help pinpoint which allergens might be causing your symptoms.

What to Expect

No special preparation is needed. You’ll have a quick blood draw, and results are typically ready within a few days to a week.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

This test plays a key role in diagnosing allergic conditions, guiding allergy treatments (like immunotherapy), and helping avoid exposure to known triggers that worsen symptoms.

Short name

IgE to Common Household Allergens

Frequently asked questions

How long will I need to wait for results?
Results are usually available within 5–7 business days, depending on lab processing times. Your healthcare provider will discuss them with you.
Can I take allergy medication before this test?
Yes, you can take prescribed allergy medications (like antihistamines) before testing, as they won’t interfere with the results. Avoid over-the-counter decongestants if instructed by your doctor.
Does this test cover outdoor allergens too?
No, this test focuses only on indoor allergens. If outdoor allergies (like pollen) are suspected, additional testing may be needed.
