Undiagnosed tuberculosis (TB) and multidrug-resistant TB remain significant global health challenges. Recent advancements in TB diagnostics offer improved tools for detection and control, focusing on cost-effectiveness and clinical impact.
Area of Science:
- Medical diagnostics
- Infectious disease epidemiology
- Public health
Background:
- Significant global burden of undiagnosed tuberculosis (TB) and multidrug-resistant TB (MDR-TB).
- Reliance on outdated diagnostic technologies hinders effective epidemic control.
- Urgent need for improved diagnostic tools to address the TB crisis.
Purpose of the Study:
- To review recent advancements in TB diagnostic technologies.
- To describe currently available diagnostic tools for TB and MDR-TB.
- To outline criteria for evaluating future diagnostic tests.
Main Methods:
- Literature review of TB diagnostic development over the past decade.
- Analysis of improvements in existing technologies.
- Evaluation of newly developed and implemented diagnostic tools.
Main Results:
- Substantial progress in the TB diagnostics developmental pipeline.
- Improvements and innovations in diagnostic technologies are available.
- Emerging tools offer enhanced detection capabilities.
