Allergy Testing

Allergy Testing is very important because it can not only save lives, but it can also inform doctors on what their patients might be allergic to. During the skin prick test, the most common test, the patient’s skin is exposed to suspected allergy-causing substances called allergens then observed for signs of a reaction. Blood tests are used as a substitute for skin tests for those who can’t undergo skin tests.

In adults and teens, the skin prick test is usually performed on the forearm and can test up to 50 different substances at once. For preschoolers, allergy testing can test up to 18 allergens and for babies four to six months old, it can test three to five allergens.
