To support countries in their efforts to strengthen detection of TB disease and infection, the World Health Organization (WHO) has published an updated version of the WHO operational handbook on tuberculosis: module 3:diagnosis,to accompany the WHO consolidated guidelines on tuberculosis published earlier this year. The document provides laboratory personnel, clinicians and other clinical staff, as well as ministries of health and technical partners, with detailed guidance on implementing WHO evidence-based recommendations. Furthermore, it describes operational considerations for the use of WHO-recommended tests, providing an overview of all testing classes, presenting revised model algorithms, and outlining the steps and processes required to implement and scale up new tests and testing strategies.
