GLI/NDWG Meeting report on high-priority target product profiles for new TB diagnostics

Diagnostic manufacturers are increasingly expressing the need to be informed about the type of TB diagnostics they should invest in, as well as the potential market size for these products. The development of target product profiles (TPPs) is therefore an important step to align the needs of end-users with the specifications and targets that product developers should meet in terms of the performance and operational characteristics of such tests. Consensus on the minimal and optimal specifications of four different types of TB diagnostic tests has been reached following a meeting convened by WHO on behalf of GLI and the New Diagnostics Working Group.
