GeneXpert® Edge (GX-Edge) is a new point-of-care platform not yet tested in the field. In this proof-of-concept study conducted for the diagnosis of tuberculosis in communities living alongside two large rivers of the Brazilian Amazon, we demonstrate that GX-Edge implemented in boats to offer onsite testing is a feasible strategy to investigate potentially devastating diseases such as tuberculosis in difficult-to-reach populations, such as riverside communities.
