T-SPOT.TB test physicians

The TB test for clinicians

tb test for physicians

Between the people and TB, there’s you

Whether you are work in pulmonology, infectious disease, or are a specialist working with patients who are considered “high-risk” for TB, you face the challeng of finding a tuberculosis (TB) test that is reliable for all your patients, even those with weakened immune systems – the immunocompromised1. In fact, many adults have been told that they are immunocompromised1, which when you don’t use the correct assay can lead to inaccurate TB test result2.

This is why you need a TB test that is reliable across patient populations.

A moment of truth

As a physician, your goal is to offer your patients a reliable TB test with results you can trust. A positive test result may mean the start of treatment that may protect both the patient and the wider community from a deadly risk. A negative test result may spare the patient exposure to powerful antibiotics. You need an answer you can trust. An accurate TB test along with your clinical evaluation of the patient will give you that answer. By finding and treating TB, you are doing your part to help eradicate TB.

The T-SPOT.TB test advantage

  1. Reliable in the immunocompromised

    The T-SPOT.TB test mitigates the risk that a low T cell count will impact patient results.3 This is especially critical in immunocompromised patients, including4,5 :

    • HIV/AIDS
    • Persons on anti-TNF and other immunosuppressive therapies
    • Chronic renal failure, including those on dialysis
    • Diabetes
    • Cancer

    In these patients, disease state or drug treatment may lead to low cell count or low cell function. With the T-SPOT.TB test, every patient gets a test with the same high sensitivity of 98.8%.6

  2. Consistent results7,8

    98.9% concordance and invalid rate < 1%

  3. No on-site incubation or refrigeration6

    Standard phlebotomy, no on-site pre-analytical steps

Interferon-gamma release assay

The T-SPOT.TB test is a T cell based interferon-gamma release assay (IGRA), designed to enable accurate results across patient populations, even in patients with a weakened immune status. The T-SPOT.TB test separates T cells from whole blood and standardizes the number of these cells in each patient test well. The T-SPOT.TB test also washes the cells to remove potentially interfering substances that can affect test results.6 The inclusion of these steps in the T-SPOT.TB test design mitigates the risk of false or invalid test results.
