About the Test

T-SPOT.TB – The EASY Blood Test for Tuberculosis

The T-SPOT.TB test is a unique, single-visit blood test for tuberculosis (TB) screening, also known as an interferon gamma release assay (IGRA). The T-SPOT.TB test 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 blood test does not cross react with the BCG vaccine and there is no association between T-SPOT.TB blood test results and immunocompromised status.¹

According to the Centers for Disease Control and Prevention (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
