LIAISON QuantiFERON-TB Gold Plus

The LIAISON QuantiFERON-TB Gold Plus assay is an in vitro diagnostic test for the detection of interferon-γ (IFN-γ) in human lithium heparin plasma by chemiluminescence immunoassay (CLIA) using the LIAISON XL Analyzer.

The QuantiFERON-TB Gold Plus Blood Collection Tubes, containing a peptide cocktail simulating ESAT-6 and CFP-10 proteins, are used in conjunction with the LIAISON QuantiFERON-TB Gold Plus assay to stimulate cells in heparinized whole blood. Detection of IFN-γ is used to identify in vitro responses to these peptide antigens that are associated with Mycobacterium tuberculosis infection.

The assay is a qualitative indirect test for M. tuberculosis infection (including disease). Although the assay detects IFN-γ quantitatively, the interpretation of the result for a single patient is strictly qualitative.

The LIAISON QuantiFERON-TB Gold Plus assay must be performed using only the LIAISON XS or LIAISON XL Analyzer.

Two products are required to operate the test:

Either:

• 311010 LIAISON QuantiFERON-TB Gold Plus - CLIA kit
• 311011 LIAISON Control QuantiFERON-TB Gold Plus - Controls kit

Or:

• 311050 LIAISON QuantiFERON-TB Gold Plus - CLIA kit
• 311051 LIAISON Control QuantiFERON-TB Gold Plus - Controls kit

Product availability may vary from country to country. Consult your regional QIAGEN sales representative for more details.
