Resources for persons who have tested positive for COVID-19. The primers only amplify genetic material from the virus, so it is unlikely a sample will be positive if viral RNA is not present. Tests that are noted with an "H" in the Authorized Settings are limited to use in laboratories certified under CLIA that meet requirements to perform high-complexity tests. A positive PCR test does not yield any information about potential immunity. As such, State licensing laws may need to be consulted to determine exactly who can use or order an EUA-authorized COVID-19 test.

Screening testing for COVID-19 looks for infections in individual people even if there is no reason to suspect the specific person has an infection or known COVID-19 exposure. Some examples of screening testing include testing by a workplace or school of all employees, students, and/or faculty returning to the workplace or school regardless of exposure or signs and symptoms, with the intent of using those results to determine who may return or what protective measures to take on an individual basis.
