Practical manual on tuberculosis laboratory strengthening, 2022 update

This handbook offers practical guidance for providing technical assistance on the implementation of WHO recommendations and international best practices for TB laboratory services. It is not intended to be a comprehensive manual or to repeat information provided by other guidance documents; hence, it contains references and links to original resources. In particular, the reader is referred to the WHO consolidated guidelines on TB for the most recent policies and to the WHO operational handbooks on TB (especially Module 3) for guidance on implementing the policies.
