Generally, it is not recommended to test a person with both a TB skin test and a TB blood test.

The TB skin test is performed by injecting a small amount of fluid (called tuberculin) into the skin on the lower are of the arm. A person given the tuberculin skin test must return within 48 to 72 hours to have a trained health care worker look for a reaction on the arm.
