Allergy Testing

In order to determine which specific substances are trigging your allergies, Dr. McCrory will safely and effectively test your skin, using tiny amounts of commonly troublesome allergens.  Once you know the specific allergens causing your symptoms, you can try to avoid exposure to the allergens, get specific medical treatment, and consider immunotherapy if necessary.

An allergen is a substance that triggers an allergic reaction.  Different allergens cause different people to suffer from symptoms such as sneezing, wheezing, coughing, or itchy eyes.  Allergy testing will help determine which allergens are causing your symptoms.  Some of the most common allergens that we will test for include:  products from dust mites, proteins from furry pets, molds, tree/grass/weed pollen, and cockroach droppings.

Chronic rhinitis is the most common condition for which allergy skin testing is performed.  This condition refers to symptoms of runny nose, sneezing, nasal congestion, postnasal drip, and sinus headaches suffered on a chronic or recurrent basis.  Allergic rhinitis (Hay fever) or non-allergic rhinitis (sinus problem) can cause chronic rhinitis.

Skin testing is a procedure where the allergen of interest is pricked through the skin.  A small hive or welt develops at the site of the test if the person is allergic.  Skin testing is the most accurate and economical way of testing for allergies.  The results are available within 20 to 30 minutes.
