The T-SPOT.TB test

Between the people and TB, there’s us

As a leading diagnostic company, Oxford Immunotec’s mission is to raise TB awareness in the hopes of eradicating this terrible disease by providing an accurate diagnostic test. We partner with survivors to share their personal stories and work hard to be a leader in the fight against TB.

Cells Matter4

The T-SPOT.TB test is a blood test for TB screening performed in one visit, using one blood collection tube. The T-SPOT.TB test is an in vitro diagnostic test for the detection of effector T cells that have been specifically activated by MTB antigens and is intended for use as an aid in the diagnosis of MTB infection. The T-SPOT.TB test delivers accurate and reliable results that clinicians can depend on.

TECHNOLOGY

Isolate 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

 The T-SPOT.TB test advantage
