BACKGROUND In 2019, there were 70.8 million forcibly displaced people worldwide. Among the top causes of morbidity and mortality were measles, diarrhea, respiratory illness, and malaria. Availability of accurate diagnostics that are of low complexity, affordable, and produce timely results on site without the need for expensive laboratory equipment, extensive training, or distant transport of samples, are essential tools in the response to humanitarian emergencies (HE). Early detection of infectious diseases with epidemic potential and coordinated outbreak response, can result in significant decrease in morbidity and mortality. CONTENT This review explores the utility of point of care and rapid diagnostic tests (POCT/RDTs) in HE and presents a review and analysis of the low complexity, availability, and ease of use of these diagnostic modalities that make them helpful tools in these settings, despite the generally lower test performance metrics associated with them over conventional laboratory-based assays. We review the literature to understand how POCT/RDTs have been used in HE response to produce lifesaving information without the need for a robust system for transporting test samples to more sophisticated laboratories, as this is often prohibitive in areas affected by conflict or natural disasters. SUMMARY We propose that POCT/RDTs be considered essential healthcare tools provided to countries following a HE and suggest that UN agencies and vulnerable countries include effective RDTs in their essential diagnostics as part of their national preparedness and response plans.
