The T-SPOT®.TB test is the only TB test with sensitivity and specificity greater than 95%¹ in pivotal clinical studies.

The T-SPOT®.TB test is a unique, single-visit blood test, also known as an interferon-gamma release assay (IGRA) for TB infection. The T-SPOT.TB test is the only blood test that has demonstrated in a pivotal clinical study both sensitivity and specificity exceeding 95% and reliability in all at-risk groups.¹ The T-SPOT.TB test does not cross react with the bacille Calmette-Guerin (BCG) vaccine and there is no association between
T-SPOT.TB test results and immunocompromised status.

According to the CDC Guidelines, IGRAs (e.g. the T-SPOT.TB test) may be used in place of a TST in most situations and are preferred for BCG vaccinated individuals and for those persons who are unlikely to return for the reading of the test results.²
