The T-SPOT.TB test is a unique, single visit blood test for tuberculosis designed to reduce assay variability and maximize sensitivity, even in the immunocompromised.1


T Cells Matter1

When your test looks for signs of TB infection using T cells, it matters how many T cells you include. The T-SPOT.TB test, unlike other tests, uses the same number each time. And it’s a big number: 250,000 cells per well, four wells per test. That’s a million witnesses to infection – and a moment of truth for TB.

Patient stories


Kelly is a physician and has treated patients with tuberculosis (TB). Being a TB patient, however, was new territory for him. One of the most difficult parts of the process was the impact on his family, friends and patients, who were forced to endure months of treatment due to their contact with him. He now brings a new understanding to his practice and works tirelessly to educate others, especially those in the healthcare community.



Kate works in television sports journalism. Pregnant with her second child at the time of her TB diagnosis, Kate spent three months hospitalized away from friends and family. Doctors were unable to tell her whether the strong antibiotics used to treat the TB would have an effect on the developing fetus. Kate, fortunately, went on to deliver a healthy baby and has served as an advocate for TB survivors ever since.

Screening Matters

Every TB test result is a ‘moment of truth’. If it’s positive, then you’ve begun the process of fighting it. You can protect the patient and the wider community from a deadly risk. If it’s negative, there may be no need for powerful antibiotics – and the patient is cleared to live and work closely with others. With so much at stake, positive or negative, what’s vital is getting a result people can trust.
