How the T-SPOT.TB test works:

The T-SPOT.TB  test enumerates the response of effector T cells that have been sensitized to Mycobacterium tuberculosis.

The T-SPOT.TB  test:

  • Removes background interferon gamma to maximize sensitivity
  • Utilizes a standard number of PBMCs to correct for a patient’s immune status
  • One visit, one tube
  • Does not require special phlebotomy
  • The only TB test with a sensitivity and specificity exceeding 95% in pivotal clinical trials
