ABSTRACT

This chapter examines attempts to innovate TB diagnostics for the point of care, aimed at improving diagnosing in resource-constrained settings and cutting diagnostic delays. Drawing on ongoing and past fieldwork from global to local levels, the analysis contrasts challenges of ensuring test and treat cycles at point-of-care in local diagnostic practices with the production of evidence on the global diagnostic pipeline and on feasibility of new diagnostics for public TB control in India. The results reveal an urgent need to improve underlying processes of innovation and an important role for ethnographic studies on how diagnostics are made to work.
