The QFT-Plus advantage – four tubes, one clear result
The QFT-Plus test uses a peptide cocktail simulating M. tuberculosis proteins to stimulate cells in heparinized whole blood. Detection of interferon-γ (IFN-γ) by enzyme-linked immunosorbent assay (ELISA) is used to identify in vitro responses to these peptide antigens that are associated with Mycobacterium tuberculosis infection.
QFT-Plus uses four unique blood collection tubes enable immediate exposure to blood lymphocytes to highly specific antigens. Testing with QFT-Plus requires just 4 ml of whole blood – 1 ml in each of the 4 tubes.
