The World Health Organization (WHO) has granted prequalification to the molecular diagnostic test for tuberculosis (TB) called Xpert® MTB/RIF Ultra. It is the first test for TB diagnosis and antibiotic susceptibility testing that meets WHO's prequalification standards.

Tuberculosis is one of the world’s leading infectious disease killers, causing over a million deaths annually and imposing immense socioeconomic burdens, especially in low- and middle-income countries. Accurate and early detection of TB, especially drug-resistant strains, remains a critical and challenging global health priority.
