Environmental Allergy Testing

Allergies are extremely common and millions of Americans suffer from seasonal or perennial (year round) allergies. An allergic reaction occurs when a person’s immune system reacts to a normally harmless substance. The source of this substance, called an allergen, may be from pollen, mold, dust mites, or pet dander among others.

What to Expect at the Allergy Testing Appointment

The allergy program team at Coastal ENT, LLC utilizes the gold standard of testing, Modified Quantitative Testing (MQT). It is a two part skin test that first applies concentrated allergens to the epidermis or outermost layer of the skin utilizing a skin prick testing device. This first part of the test will give a general sense of what allergens you are sensitive to and to what degree of sensitivity. Once the skin prick test results are obtained we will then move on to Intradermal Dilution Testing (IDT). This second part of the testing requires a small amount of diluted allergens be placed just under the skin. The results of the testing are combined and our end points allow us to formulate your immunotherapy based on your specific testing results.

Please come to the appointment dressed comfortably, preferably with a short sleeved shirt as the testing is usually performed on both of the arms. Do not put any lotions, creams or perfumes on your skin the day of testing.

You should not undergo skin allergy testing if:
  • You are pregnant.
  • You have a skin condition called dermatographism.
  • You have unstable asthma, your asthma is worsening or you have been hospitalized for asthma in the past year.
  • You are taking a beta blocker for high blood pressure.
