Who needs a 2 Step TB test?
The Tuberculin Skin Test (TST) is a screening method developed to evaluate an individual's status for active Tuberculosis (TB) or Latent TB infection. The 2-Step TST is recommended for initial skin testing of adults who will be periodically retested, such as healthcare workers.
How often should PPD be done?
If you have a negative skin test, you need a repeat test at least once 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.
Is 2 Step TB test necessary?
Using a TB blood test for baseline testing does not require two-step testing. Additionally, TB blood tests are not affected by the BCG vaccine. * Note: An individual TB risk assessment should be used to help interpret test results and determine whether health care personnel are at increased risk for TB.
