Allergy Testing Q & A

What is an allergy?

An allergy is an overreaction from your immune system after it comes in contact with a harmless substance that it mistakes for a foreign invader, such as peanuts or pollen. They can range from mild responses, like an itchy throat or light rash, to life-threatening. 

What are the symptoms of allergies?

Some of the most common signs of allergies in children and adults include:

  • Sneezing
  • Watery eyes
  • Swollen tongue, lips, or face
  • Hives
  • Rash
  • Digestive problems
  • Skin irritation
  • Red eyes
  • Chest tightness
  • Wheezing
  • Nausea
  • Fatigue

Anaphylaxis is a severe, life-threatening allergic reaction that causes constriction of your airways, low blood pressure, and more.

What is allergy testing?

An allergy test is an exam in which Dr. Reidy exposes you to certain allergens  — suspected allergy-inducing substances —to see if they spark a reaction. Dr. Reidy has a number of allergy tests at his office for children and adults, including:

Skin test

There are many different skin tests Dr. Reidy provides to diagnose allergies. During a scratch test, he slightly punctures the skin. For an intradermal test, he injects a small amount of the allergen underneath the skin. If he performs a patch test, Dr. Reidy puts the allergen on a patch and sticks it to your back or arm.

Chemical sensitivity test

During a chemical sensitivity test, Dr. Reidy determines whether you’re sensitive to certain chemicals, such as formaldehyde, ammonia, or BPA.

Food testing

Dr. Reidy uses food testing to determine whether you’re allergic or sensitive to certain foods, such as milk, tree nuts, or gluten. There are several methods that can help him make a diagnosis, including a blood test, elimination diet, skin prick test (scratch test), or oral challenge test.

Immune test

An immunoglobulin test measures the number of antibodies— the proteins that fight bacteria and viruses — in your blood to evaluate their function.

Pulmonary function test

A pulmonary function test is a test that determines how well your lungs are functioning. They’re typically used to diagnose or rule out asthma.

How are allergies treated?

There are many ways to treat allergies, depending on the frequency and severity of the allergy, including:


Immunotherapy helps prevent a severe allergic reaction by training your body to become less allergic. Dr. Reidy does this by gradually giving your increasing doses of the allergen. Over time, your body becomes less sensitive to the substance. He offers allergy shots — regular injections of the allergen — and sublingual drops, which are tablets or liquid drops that he places under your tongue.


An antihistamine is a medication that can help reduce sneezing, watery eyes, and mild skin reactions.

Asthma medications

If you have asthma, Dr. Reidy may recommend a bronchodilators or an inhaled corticosteroid.
