HIN A research team funded by the National Institutes of Health has launched a study to assess performance and usability of a smartphone app paired with the Quidel QuickVue At-Home COVID-19 Test, which just received an Emergency Use Authorization (EUA) from the U.S. Food and Drug Administration for use with a prescription. The home test was supported by NIH through the Rapid Acceleration of Diagnostics (RADx) initiative, which has spurred the development and commercial availability of millions of COVID-19 tests over the past year. More than 200 participants have already enrolled in the study that involves daily testing for a two-week period. An app called MyDataHelps, developed by CareEvolution, LLC provides step-by-step instructions for taking the test and important tools such as timers to ensure that the steps of the test are performed at the correct time intervals. Although users can interpret the test result on their own, the app also provides an independent confirmation of the result when the user photographs the test strip with the smartphone camera.
