There are a few methods of skin allergy testing.
At the UPMC Sino-Nasal Disorders and Allergy Center, we use both skin prick and intradermal dilutional skin allergy testing. Both tests give precise readings of the degree of your allergy. They also allow the doctor to give allergy shots — if you need them — at the highest safe concentration.
Full skin testing will take about two hours. All skin allergy testing appointments include an in-depth environmental allergy consult and a thorough review of our immunotherapy program.
During your allergy skin test, your doctor will inject a small amount of antigen under the top layers of your skin.
The shot will make a small bump (4 mm) under the skin for the intradermal test.
If you are allergic, this bump will increase in size within 10 minutes. Your doctor will then measure the size of the bump or welt.
