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
