Tuberculosis Testing

The Port Arthur Health Department is no longer able to provide TB tests, as a mandate handed down by the state health agencies has changed. In the past, the Health Department has provided tuberculosis testing for the general public for pre-employment as well as other needs. Due to the shortage of the vaccine tubersol, the Health Department is now only allowed to test those who have come in contact with tuberculosis and certain "High-risk" individuals as stated in the TB work plan. Please contact the Port Arthur Health Department for more information.

How can you be screened for TB?

There are 2 types of tests screen for TB infection:
  • The tuberculin skin test (TST or PPD): The tuberculin skin test is a new blood test that was approved by the FDA in 2008.
  • Blood tests such as the T-SPOT.TB test. This new test is particularly important for those who have had the TB vaccination, also known as the BCG vaccination, or those who are immunocompromised.
Blood testing is offered for adults, and in special circumstances for children.

TST or PPD is read in 48-72 hours from the date it was administered.

T-SPOT report will return to our office within 4 days. If you have any questions or concerns call the numbers listed. For more information visit T-SPOT.TB, or the Centers for Disease Control and Prevention (CDC).
