For a tuberculosis (TB) test, specifically the tuberculin skin test (TST), a 26 to 27 gauge needle is typically used. The needle is usually 1/2 to 5/8 inch in length to ensure proper intradermal injection. The test involves injecting a small amount of purified protein derivative (PPD) into the skin of the forearm to check for a reaction.

Since 2001 there has been an approved blood test for TB that has advantages over the skin test, and is recommended by the US Center for Disease Control. Follow the links below for details. It does not require a repeat visit (if negative), and is more reliable in some cases, such as people who have had a TB immunization or multiple TB skin tests. It is called the QuantiFERON®-TB Gold test. Like the skin test, it only tells that a person has been infected with TB germs. It does not tell whether or not the person has progressed to TB disease. Other tests, such as a chest x-ray and a sample of sputum, are needed to see whether the person has TB disease. The test mentioned above tests for TB by detecting the immune response to TB. If a patient is severely ill, there may be TB bacilli in the blood, and a blood culture can be used.
