1 People who have a positive TB skin test with a normal chest X-ray are NOT contagious, but may need medicine to prevent them from ever getting active TB. 2  Children under the age of 12 with active TB are rarely contagious, and do not need to be kept out of school.ow often does a TB test have to be repeated? If you have a negative skin test, you need a repeat test at least every four years. If you have a documented positive skin test, you must have an initial chest X-ray. After that, you still need to be screened every four years.
The preferred term for the test is tuberculin skin test, or TST. People who have been vaccinated with Bacille Calmette-GuÃ©rin (BCG) should not be exempted from TB skin testing unless they have a documented positive result from a prior test. Disregard BCG history when interpreting TST results.
