The QIAreach QuantiFERON-TB is a portable device that enables the ultrasensitive digital detection of TB infection with an end-to-end workflow that is simple and cost efficient, and increases access to reliable Interferon Gamma Release Assay (IGRA) testing. Built on the proven QuantiFERON-TB Gold Plus technology, it uses blood samples to test for interferon-gamma molecules released from T-cells that have come into contact with TB bacteria. QIAreach QuantiFERON-TB runs these tests on the digital eHub and eStick system, a true walkaway solution with random access and no calibration or maintenance. QIAreach QuantiFERON TB testing requires one patient visit and produces an easy-to-read result in 20 minutes after sample incubation, with the ability to record and send results for improved data management, making it ideal for TB screening programs.
