A recent study demonstrated the high sensitivity and specificity of AAZ COVID-PRESTO, a Point of Care (POC) COVID-19 diagnostic test. Prazuck et al. thus aimed to evaluate users’ ability to obtain and interpret test results from the COVID-PRESTO and to understand its efficacy outside a laboratory setting. Non-medically trained participants (n=143) were recruited from four sites in Central France between March and April 2020. Participants viewed instructional media on using the self-test, administered the test and filled out satisfaction questionnaires. Participants were also asked to interpret standardized test results. The written and video instructions were found to be comprehensible by 88.5% and 90.7% of the participants, respectively. Nearly all participants (98.6%), were able to obtain a valid test result, and 94.3% of participants were satisfied with the COVID-PRESTO POC test, rating it as “good,” “very good”, or “excellent.” Out of the 288 tests read by participants in their assessment, the success rate was 99.3% (only two were interpreted incorrectly). Age and education were not found to significantly impact the level of instruction comprehension or test usability. Authors conclude that COVID-PRESTO demonstrates potential as a POC test for the wider public.
