What the trial is, and whether it could suit you

Tuberculosis (TB) is one of the leading causes of infectious disease worldwide. The diagnosis of TB typically relies on microbiological evidence of the presence of Mycobacterium tuberculosis (MTB) or histological features of the host immune response to MTB in the infected organs. The diagnosis can be enhanced by performing molecular diagnostic tests (e.g. polymerase chain reaction, PCR) on the clinical specimens obtained. Expectorated sputum is usually the first sample sent for MTB culture for suspected pulmonary TB (PTB), which is the most common type of TB. However, this can be particularly challenging for paediatric patients and elderly patients with poor coughing techniques or effort. While for extrapulmonary TB (EPTB), which contributes to 10-20% of TB cases, with TB pleuritis and lymphadenitis as the most common types, invasive investigations are usually required for obtaining clin
