Wheal: The tuberculin skin test is administered to the upper third of the forearm (palm up) ≥2 inches from elbow, wrist, or other injection site. If neither arm can be used, it can be given in the back of the shoulder. Use a 1/4 to1/2 inch 27-gauge needle or finer tuberculin syringe. It should form a wheal 6-10 mm in diameter, and it is interpreted 48-72 hours later.
