Competing Interests

The Academic Editor, Madhukar Pai, declares that he consults for the Bill & Melinda Gates Foundation (BMGF). The BMGF supported the Foundation for Innovative New Diagnostics (FIND), which was involved in the development of the Xpert MTB/RIF assay. He also co-chairs the Stop TB Partnership's New Diagnostics Working Group that was involved in the WHO endorsement of the Xpert assay. The authors declare that the University of Cape Town (Mark Nicol as Principal Investigator) has received research funding from FIND to conduct research around the evaluation and impact of GeneXpert MTB/RIF technology. All other authors have declared that no competing interests exist.
