Description
The LIOFeron®TB/LTBI is a cytokine release assay for quantitative determination of Interferon Gamma (IFN-γ) produced by human blood cells stimulated with Mycobacterium tuberculosis antigens. Thus, the test is useful for the diagnosis of Latent TB Infection (LTBI). As for other IGRA tests on the market, this test may react positive in TB patients also, but it cannot differentiate between LTBI and active TB.
