QuantiFERON® TB-Gold in Tube

QuantiFERON® TB-Gold is an ELISA test for the detection of M. tuberculosis in immunocompetent individuals. The analysis is particularly relevant in those who have received the BCG vaccine, as the analysis, in contrast to skin tests with tuberculin (Mantoux), can distinguish between infection with M. tuberculosis and vaccination.

Clinical relevance

QuantiFERON® TB-Gold is an ELISA test for the detection of M. tuberculosis in immunocompetent individuals, for example, as part of infection detection, screening of high-risk groups, in special cases for the detection of active tuberculous disease and before treatment with immunosuppressive drugs. In the case of infection with M. tuberculosis, the immune response is predominantly cell mediated. In infected immunocompetent individuals, stimulation of blood with specific antigens (ESAT 6, CFP 10 and TB 7.7) will cause T lymphocytes to release the cytokine interferon gamma, which is detected by ELISA.

Product description

QuantiFERON® TB Gold consists of an ELISA kit and blood collection tubes, which can be ordered separately. For sampling, four blood collection tubes are used: 1x Nil; 2x TB Ag and 1x Mitogen. The tubes are delivered as a combined package or in bulk. In the laboratory, up to 58 tests can be performed per ELISA kit. SSI Diagnostica distributes QuantiFERON®TB-Gold Plus in Denmark, Iceland, Norway and Sweden on behalf of Qiagen.
