question: Can self-tests (also known as over-the-counter or home tests) be used when determining when healthcare personnel (HCP) with SARS-CoV-2 infection or higher-risk exposures may return to work?
answer: Viral testing is recommended following a higher-risk exposure and might also be used to inform when HCP with SARS-CoV-2 infection may return to work. Using laboratory-based or point-of-care tests are generally preferred in these situations; these tests help ensure the test was administered correctly by a trained provider and allow for official results to be shared with occupational health services. Use of self-tests might be considered in some situations. However, such an approach may inappropriately transfer the cost of testing to HCP, Requires trust that HCP self-administered and interpreted the test results correctly, and Requires that HCP report their own results to occupational health services. If self-tests are used, consideration should be given to performing a second test at least 24 hours following an initial negative test; if negative, this increases the confidence the HCP are not infectious. Facilities could also consider having HCP present for a proctored test to assist with ensuring appropriate collection and interpretation.  CDC has resources to assist individuals with self-testing.
