About test

QUANTIFERON TB-GOLD (QFTA) is an FDA-approved blood test that serves as a surrogate marker for M. tuberculosis and can assist in the diagnosis of (but cannot differentiate) active or latent tuberculosis. QFT is an interferon-gamma release assay (IGRA) that measures the patient's cellular immune response by sensitized lymphocytes to PPD (purified protein derivate) antigens derived from M.tuberculosis. The assay is not affected by BCG vaccination.
