A negative reaction usually means you have never been infected with the bacteria that cause TB. With a negative reaction, the skin where you received the PPD test is not swollen, or the swelling is very small.
After an exposure to infectious tuberculosis, a TB skin test reaction of 5 mm induration or greater is considered positive. You will then be evaluated for signs and symptoms of active tuberculosis (cough lasting for more than three weeks, bloody sputum, fever, night sweats, weight loss, loss of appetite, fatigue).f you are exposed to someone with infectious tuberculosis and have never had a positive reaction to the tuberculin (TB) skin test, you should have a baseline test within 3 months prior to the exposure date.
