Use of Tuberculosis Interferon-Gamma Release Assays (IGRAs) in Low- and Middle- Income Countries: Policy Statement. Geneva: World Health Organization; 2011.

6Implications for further research

Targeted further research to identify IGRAs with improved accuracy is strongly encouraged. Such research should be based on adequate study design and including quality principles such as representative suspect populations, prospective follow-up and adequate, explicit blinding. It is also strongly recommended that proof-of-principle studies be followed by evidence produced from prospectively implemented and well designed evaluation and demonstration studies, including assessment of patient impact.
