Overview

The "WHO consolidated guidelines on tuberculosis. Module 3: diagnosis"combines the WHO policy guidance on detection of TB infection, disease and drug resistance into a single reference document. Compared to the previous edition, the updated guidelines present new recommendations on concurrent testing of respiratory and non-respiratory samples among people of all ages living with HIV and children without HIV or with unknown HIV status; establish two new classes of TB diagnostic technologies for the initial detection of TB and resistance to rifampicin, and; outline current WHO TB diagnostic class determination and product assessment definitions and pathways

This document will be accompanied by the "WHO operational handbook on tuberculosis. Module 3: diagnosis", which aims at facilitating implementation of the WHO recommendations by Member States, technical partners, and others involved in managing patients with TB infection, TB disease, and drug-resistant TB.
