Needles, Tine Test
Definition : Needles designed for tine (tuberculin) tests. These devices consist of a set of needles (typically four) attached to a plastic handle and coated with drip-dried tuberculin (a dried broth of Mycobacterium tuberculosis). The set of needles is pressed into the skin of the forearm, where it deposits a preestablished dose of tuberculin. Any induration greater than or equal to 2 mm in diameter around one or more of the puncture sites after 48 to 72 hours is considered a positive result for this test.
