A small needle is inserted on your forearm and a material called tuberculin is injected under your skin. A healthcare worker or your Physician then reads the test in 2-3 days. If you have a “bump” of a certain size where the skin test was administered it means you could possibly have a TB infection and your Physician will order a chest x-ray and sputum culture.
