TRIAL DESCRIPTION
Public title GeneXpert Demonstration Study MTB/RIF
Official scientific title The impact of rapid molecular diagnosis of tuberculosis on tuberculosis services and patient care ¿ a cluster randomized trial
Brief summary describing the background
and objectives of the trial
GeneXpert MTB/Rif is a simple automated real-time PCR test for the diagnosis of TB and identification of rifampicin resistance, performed directly on sputum samples. In a recently completed evaluation study GeneXpert showed high sensitivity for both smear negative and positive disease. We aim to evaluate the impact of this diagnostic test on time to treatment and proportion of patients with undiagnosed TB two months after initial presentation to the health care facility.
