Allergy Testing

Learn more about your allergies.

Skin testing can determine allergies to pet dander, dust and dust mites, insects,  foods, mold and mildew, and grass, tree, or weed pollens. Skin tests are done by placing little drops of each suspected allergen on your back then lightly pricking the skin with a plastic applicator to break the top layer; also sometimes small needles actually inject the allergen directly under the skin (intradermal testing). If the skin is itchy, red or has welts it is then scored on a zero to four scale to determine which allergen you are allergic to.
