Development of an At-Home COVID-19 Test Results–Reporting System for a School District Primarily Serving Underrepresented Minority Groups, San Diego, CA, 2021–2022

School-sponsored at-home COVID-19 testing benefits users, school administrators, and surveillance efforts, although reporting results remains challenging. Users require simple systems with tailored posttest guidance, and administrators need timely positive test information. We built a system to serve these needs and to collect data for our Rapid Acceleration of Diagnostics-Underserved Populations Return to School Program study in San Diego County, California, from October 2021 through January 2022. We describe this system and our participant outreach strategies and outline a replicable model for at-home results reporting.
