The T-SPOT.TB test is an in vitro diagnostic test that enumerates the response of effector T cells that have been sensitized to Mycobacterium tuberculosis.   The T-SPOT.TB test is the only blood test that has demonstrated in a pivotal clinical study both sensitivity and specificity exceeding ninety-five percent and reliability in all targeted groups.   

T-SPOT.TB is a serious solution that provides clinical confidence:

• 95.6% Sensitivity¹
• 97.1% Specificity¹
• Results unaffected by BCG vaccination, age or immunosuppression²

Benefits of the T-SPOT.TB test are:

• Single blood test, no repeat visit required
• Fast:  next day results
• Cost effective
• No special lab equipment required
• "One and Done" (no second visit required to read test results)

The T-SPOT.TB test addresses the unique requirements for all groups tested for TB:

The body of scientific evidence continues to grow on the performance of the T-SPOT.TB test.  A significant number of studies have been published worldwide in a variety of clinical and epidemiological settings.  These studies show consistent and reproducible results and demonstrate the test's universal utility for the diagnosis and control of TB.
