T-Cell Select has been FDA-approved for the automation of the T-SPOT.TB test workflow
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
PERFORMANCET 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.
TECHNOLOGYIsolate PBMCs
Enriches the desired cell population (T cells) from whole blood
Wash cells
Enables removal of serum and potentially interfering substances
Count cells
Facilitates correction for variations in patient PBMC counts
Standardize cells
Ensures that the required number of cells are used to produce a reportable result
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.
Latest Guidelines
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.
