At NorthShore, our experts offer various allergy testing options to help determine what substance is causing an allergic reaction. In a skin test, a small amount of the allergen is placed on or below the skin. For those patients unable to have a skin test, a blood test may be used to identify antibodies in the blood in response to allergens.
Depending on the results of the allergy testing, patients may receive allergy shots or immunotherapy. The goal of these treatment options is to help reduce allergy symptoms over time.
