Tuberculosis (TB) screening test, also known as QuantiFERON-TB Gold (QFT-G) or
TB Platinum QuantiFERON is used for screening tuberculosis. This test can be
done when you have a high risk of exposure to TB. TB is an infectious disease
caused by the bacterium Mycobacterium tuberculosis. TB primarily targets the
lungs but may affect any area of the body such as the urinary tract, central
nervous system, bones, joints, and/or other organs. The screening test measures
the body's immune response to antigens derived from these bacteria.
