If you experience little to no allergy relief after taking antihistamines, your doctor may schedule you for skin prick testing. The test is performed on the inner forearms and back, and your reactions are measured after 20 minutes. After testing, your allergy nurse will go over your results with you.
During the procedure, we will test for allergies to the following seasonal and year-round allergens, including dander, fungus, grass, mold, tree pollen, weeds and yeast.
