QuantiFERON-TB Gold is an in vitro diagnostic test to aid in the detection of Mycobacterium tuberculosis infection. It combines the simplicity of the QuantiFERON technology with the diagnostic power of synthetic TB-specific peptides (ESAT-6 and CFP-10) to provide the best available method of diagnosing TB infection.
Because QuantiFERON-TB Gold uses whole blood, with no need for cell isolation and fractionation, it is inexpensive and fast. The assay measures Interferon-gamma (IFN-) secreted from stimulated T-cells previously exposed to M. tuberculosis to assess TB infection status.
In the Laboratory:
Rapid test, results available within 24 hours
Highly reproducible in vitro procedure
Simple procedure, low equipment & labor costs
Use of whole blood is safer, easier, less labor with no cell isolation and counting
The QuantiFERON-TB Gold test is approved by the US FDA for in vitro diagnostic use (December, 2004), is approved for sale in Japan (April, 2005), and has CE Marking for use in Europe.
