DiaSorin LIAISON QuantiFERON-TB Gold Plus

The DiaSorin LIAISON® QuantiFERON®-TB Gold Plus assay uses chemiluminescent immunoassay (CLIA) technology for the detection of interferon-γ (IFN-γ) in human lithium heparin plasma specimens. The immunoassay can identify in vitroresponses to a peptide antigens cocktail associated with Mycobacterium tuberculosis (M. tuberculosis) infection (including disease) that stimulates cells in heparinized whole blood collected with the QuantiFERON®-TB Gold Plus Blood Collection Tubes. The assay is an indirect test intended as an aid in the diagnosis of M. tuberculosis infection. Although the assay quantitatively detects the IFN-γ, the interpretation of the result for a single patient is strictly qualitative. The assay must be performed on the LIAISON® XL and LIAISON® XS analyzers only.
