Environmental Allergy Testing Q & A

​

What is environmental allergy testing?

Environmental allergy testing is a diagnostic procedure used to identify irritants in your environment — like pollen, mold, dust mites, or pet dander — that may be triggering your allergy symptoms.

​

This type of testing gives your allergist the information needed to develop a targeted treatment plan, which may include strategies to reduce exposure, medications, and/or long-term options like allergy shots.

​

How does allergy testing work?

Environmental allergy testing typically involves skin testing and/or a blood test:

• Skin prick test: Small amounts of the allergens are placed on your skin (usually the forearm or back) using a tiny applicator that does not penetrate the skin. If you’re allergic, a small raised bump and redness will appear. 

• Intradermal test: If your initial skin prick test is negative but your allergist still suspects an allergy, intradermal testing may be recommended. This test is more sensitive and can detect allergies the skin prick test might miss. A small amount of allergen is injected just beneath the surface of your skin using a fine needle. If you’re allergic, a small raised bump and redness will appear.

• Blood test: A sample of your blood is analyzed to check for allergen-specific antibodies (IgE) in response to certain environmental triggers.

 

Your allergist will determine which tests are right for you based on your symptoms and medical history.

​

What symptoms can allergy testing help diagnose?

Testing can identify the causes of allergy symptoms such as:

• Sneezing

• Runny or stuffy nose

• Itchy, watery eyes

• Postnasal drip

• Coughing

• Wheezing or shortness of breath
   

If you experience any of these symptoms — especially if they occur seasonally or in certain indoor environments — environmental allergy testing may be beneficial.

​

Who should consider allergy testing?

You may benefit from testing if:

• You experience chronic allergy symptoms that interfere with your daily life

• Over-the-counter medications aren’t effective

• You’re considering long-term treatments like allergy shots

• You’re unsure which allergens are triggering your symptoms

• You have asthma
   

Testing can be done for both children and adults.

How do I get tested for environmental allergies?

To begin, schedule an appointment with the specialists at Allergy and Asthma Specialists of Greater Washington. Your provider will review your medical history and symptoms to determine the best testing approach.

Environmental allergy testing is the first step toward long-term relief from your symptoms. Once your triggers are identified, you and your allergist can create a plan that may include environmental controls, medications, or allergy shots.
