WHO's new TB diagnostics playbook is here. The World Health Organization has published its first-ever Guidance on Evidence Generation (GEG) for new tuberculosis diagnostics, giving researchers, developers, and funders a clear framework for producing the evidence needed to shape WHO policy. The goal: get better, faster-adopted TB tests to the people who need them most.
WHO's new TB diagnostics playbook is here. The World Health Organization has released its first-ever Guidance on Evidence Generation (GEG) for new tuberculosis diagnostics — the third in a series of GEG documents following similar guidance on TB treatment and preventive treatment regimens. The document is designed to help researchers, developers, and funders generate high-quality, policy-ready evidence on new TB diagnostic tests, sample types, and testing strategies.
The guidance tackles a longstanding problem: evidence for new TB diagnostics has often been incomplete, methodologically flawed, or focused too narrowly on test accuracy while ignoring factors like feasibility, equity, and cost-effectiveness. A new analytical framework maps a diagnostic's role across the clinical pathway and links it to key study design and reporting considerations.
Key Takeaways:
Why it matters: Stronger, more complete evidence means WHO can make faster, more robust recommendations — ultimately accelerating the adoption of innovative TB diagnostics in the countries that need them most.
