The Stop TB Partnership’s Global Drug Facility (GDF) has expanded its Diagnostics Catalog by adding an IGRA (interferon-gamma release assay) test for latent TB infection. The products required to run the QuantiFERON-TB Gold Plus (QFT-Plus) IGRA are now available at a GDF-negotiated price of $15.90 per test by the manufacturer Qiagen (Hilden, Germany). This price is offered to any public sector or not-for-profit buyer in low- and middle-income countries when procuring through GDF.
