Qiagen Introduces QuantiFERON-TB In China
QIAGEN has launched its QuantiFERON-TB gold in-tube, a blood test that can accurately identify people infected with Mycobacterium tuberculosis, in China. QIAGEN already sells QuantiFERON-TB in many markets, including the US and Europe, and gained approval earlier in 2014 from the China FDA.
QIAGEN's QuantiFERON-TB is an interferon-gamma release assay (IGRA), a blood test that is claimed to be faster, more accurate and cost-effective than older methods. QuantiFERON-TB can reduce false-positive readings caused by the Bacille Calmette-Guérin vaccination, which newborns in countries such as China receive as a matter of policy.
