Contact a nearby pharmacy, as Walgreens and CVS both have clinics that perform tuberculosis testing, note Walgreens and CVS. University students can contact their campus health clinic, as TB tests are available there, notes University of Texas at Dallas.
Another option is a local testing service such as Labcorp. These offices offer a number of different medical tests, as listed on its website.
For a TB skin test, the technician injects fluid containing some of the TB organism beneath the skin, and exposure to TB or receiving the Bacillus Calmette-Guerin vaccine leads to a hard area forming at the injection site. This positive result requires blood testing and X-rays to confirm active tuberculosis, notes Walgreens.
