QuantiFERON-TB Gold Plus is approved for use as an aid in diagnosing M. tuberculosis infection, including both latent tuberculosis infection (LTBI) and tuberculosis (TB) disease. The CDC recommends that the QuantiFERON-TB Gold Plus can be used in place of tuberculin skin testing (TST) in all circumstances. The QuantiFERON-TB Gold Plus test is not affected by previous vaccination with bacille Calmette-Guerin (BCG) and can be used for those patients, unlike the TST.
