[Diagnostic accuracy of three technologies for the diagnosis of multi-drug resistant tuberculosis].

Introduction: Multi-drug resistant (MDR-TB) and extensively drug-resistant (XDR-TB) tuberculoses are a global public health problem. Their timely detection might reduce the burden of the disease and the economic impact on health systems worldwide.

Objective: To conduct a literature review of the diagnostic accuracy of three molecular tests to detect multi-drug resistant and extensively drug-resistant tuberculoses.
