The QuantiFERON-TB Gold Plus blood test measures your immune response to Mycobacterium tuberculosis. Unlike the traditional skin test, it requires only one visit, is not affected by prior BCG vaccination, and has fewer false positives. It's required for many employment, school, and immigration purposes. A positive result indicates TB exposure but does not distinguish between latent and active TB infection.
