With a growing list of new platforms, end-user acceptability is an evolving topic in point-of-care (POC) test development. Although technical reports of new experimental POC tests are common, it is rare to find reports that evaluate the end-user acceptability of such innovations. This work illustrates an example of bridging that gap by evaluating the end-user acceptability of an experimental POC test platform with novel technical features. A prototype smartphone-based sexually transmitted infection tests was evaluated by emergency department technicians, followed by a survey of acceptability factors. Our findings suggest that the end-user acceptability of some design features be implemented in the prototype.
