The T-SPOT.TB test is the only IGRA cleared by the FDA for ages two and up1
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.1PERFORMANCE
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.TECHNOLOGY
Enriches the desired cell population (T cells) from whole blood
Enables removal of serum and potentially interfering substances
Facilitates correction for variations in patient PBMC counts
Ensures that the required number of cells are used to produce a reportable result
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.

Shaka teaches and performs as a salsa dancer. His passion has taken him around the world. When he was diagnosed, he learned that he had disseminated TB, or TB that had spread from his lungs to other parts of his body.

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.
US TB testing guidelines broadly recommend IGRA testing. Periodically, various institutions issue updated tuberculosis (TB) testing guidelines for different populations. This section is a resource, compiling these TB testing guidelines for your convenience and guidance.
