Allergy Tests (Allergy Skin Testing)

Allergy tests (allergy skin testing) can identify the presence of a certain types of common allergies that are often involved in causing the symptoms of ear, nose and throat allergy, asthma, skin allergy, anaphylaxis, drug allergy, food allergy and insect sting allergy.

There are main two types of allergy tests performed in our office:

  •  

 

Allergy Tests – Prick

Drops of allergens are placed on the patient’s back and subsequently slightly pricked with a special device in order to expose the skin to the allergen. When the allergy test is positive, a hive forms at the site of exposure just beneath the allergen. The larger the hive the more allergic the patient is to that specific allergen. This is an excellent screening test for the presence of strong allergy. Negative tests are repeated using the more sensitive intradermal technique.

  •  

 

Allergy Tests – Intradermal

Intradermal allergy tests are
much more sensitive in detecting mild to moderate allergy than prick testing. Small amounts of allergen are injected just under the skin of the upper arm using a very small needle.

Additionally, in infants and young children, a multi-test device is used instead of individual allergy testing, of which is exceedingly fast to apply and minimizes testing time for the child.


Allergy tests usually takes about one hour. It is very accurate and sensitive and essential to many of our recommendations for treatment. We recommend our patients wear a short-sleeve shirt on the day of the appointment in case intradermal testing is performed.

Antihistamines can interfere with allergy testing.  No prescription or over-the-counter antihistamines should be used 3 days prior to allergy skin testing. Asthma medications should not be stopped.

Our specialists perform allergy tests for both children and adults at all of our 9 locations throughout Delaware Valley including Philadelphia (Center City, Society Hill, Northeast), The Main Line (Bala Cynwyd), Bucks County (Langhorne), and South Jersey (Mt. Laurel, Woodbury, Hamilton, Forked River).
