Allergy Testing Q & A

What causes allergies?

Allergies begin when your immune system reacts to a safe substance and labels it as a danger to your body. Every time you breathe in that substance in the future, your immune system releases chemicals that cause an allergic reaction.

Allergic rhinitis, sometimes called hay fever, is one of the most common types of allergies. It’s caused by substances you breathe in, such as:

  • Pollen (from trees, weeds, and grasses)
  • Dust mites
  • Pet dander
  • Mold spores


Allergic rhinitis often appears at certain seasons when plants release pollen. For example, tree pollen is high in spring, grass pollen causes hay fever in late spring and summer, and then ragweed season begins in late summer and lasts until the first frost.

What symptoms develop due to allergies?

Airborne allergies cause one or more of the following symptoms:

  • Sneezing
  • Fatigue
  • Runny nose
  • Congested nose
  • Red, watery eyes
  • Itchy nose and eyes
  • Swelling around your eyes


Allergies are often associated with fatigue, usually, because your symptoms disrupt your sleep.

What should I know about allergy testing?

Dr. Sycamore performs a skin test to determine the allergens responsible for your symptoms. Before performing the test, he evaluates your symptoms and medical history to narrow down the potential allergens.

The skin test is usually done on the inside of your arm, which is marked with lines and numbers that track which allergen was applied in that spot. Then your provider places a small drop of allergen at each marked area and gently pricks your skin under each allergen.

After your skin is pricked, you’ll wait in the office for about 15 minutes. If you’re allergic to any of the substances, you’ll develop a red, itchy bump at the site where it got under your skin.

How do you treat allergies?

Once Dr. Sycamore knows your allergens, he can help you create a plan to avoid them and recommend or prescribe medications to relieve your symptoms. If your symptoms don’t improve or they get worse, you may be a good candidate for immunotherapy.

During immunotherapy, you receive a very small dose of your allergen, either through an injection (allergy shots) or a tablet placed under your tongue (sublingual immunotherapy). Over time, regular exposure to the allergen desensitizes your immune system so your symptoms are significantly diminished or eliminated.
