To read a tuberculosis skin test, start by going to the doctor for a test, which involves an injection that will cause a welt on your arm. If the welt is a soft bump, the results are likely negative. However, if it's a hard, dense, raised formation, the results may be positive. Doctors should read skin tests 48-72 hours after the injection. The basis of the reading of the skin test is the presence or absence and the amount of induration (localized swelling). A negative test does not always mean that a person is free of tuberculosis. A TB skin test requires two visits with a health care provider.
