TB PCR in BAL and EBUS-TBNA

Brief summary (registry, in English)

This prospective observational multi-centre UK study will evaluate Xpert MTB/RIF Ultra for the detection of Mycobacterium tuberculosis (MTB) in bronchoalveolar lavage (BAL) samples for pulmonary TB and endobronchial ultrasound guided transbronchial needle aspiration (EBUS-TBNA) samples for mediastinal TB and compare the diagnostic performance against conventional modalities (smear, culture, cytology) as well as to a clinical composite diagnosis. This will be using a clinical expert panel reviewing data blindly. The Investigators will assess the performance of Xpert Ultra by calculating the sensitivity, specificity, positive predictive and negative predictive value in UK centres. The turn-around time of these modality and its effect on treatment decisions will be assessed. Finally the Investigators will correlate different clinical characteristics and to define the sensitivities in the various clinical presentations and to evaluate the phenotypes of patients with 'trace' results within these cohorts.
