T-SPOT.TB, a form of ELISpot, the variant of ELISA (licensed in Europe, US, Japan and China). [ 3 ] The former test quantitates the amount of IFN-γ produced in response to the ESAT-6 and CFP-10 antigens from Mycobacterium tuberculosis , which are distinguishable from those present in BCG and most other non-tuberculous mycobacteria .
T-SPOT.TB counts the number of antimycobacterial effector T cells, white blood cells that produce interferon-gamma, in a sample of blood.This gives an overall measurement of the host immune response against mycobacteria, which can reveal the presence of infection with Mycobacterium tuberculosis, the causative agent of tuberculosis (TB).
