How are the TB tests given?

For a TB skin test, a health care worker uses a small needle to put some testing material, called tuberculin, just under your skin. This is usually done on the lower inside part of your arm. After you get the test, you must return in 2 to 3 days to see if there is a reaction to the test. If there is a reaction, the size of the reaction is measured.
