People who have symptoms of COVID-19 or who have had known close contact to someone with COVID-19 should be tested for COVID-19.

• Point-of care serial screening testing can provide rapid results and is critical to identifying people with COVID-19 who do not have symptoms and slowing the spread of SARS-CoV-2. This is especially important when community risk or transmission levels are substantial or high.
• When selecting which SARS-CoV-2 test to use and interpreting results, healthcare providers, public health professionals, and those organizing and implementing testing should consider the context in which they are being used, including the prevalence of SARS-CoV-2 in the population being tested and the status (signs, symptoms, close contacts) of the person being tested.
• A person’s vaccination status does not affect the results of their viral test for SARS-CoV-2.
• This guidance has been developed based on what is currently known about SARS-CoV-2 infection and COVID-19 and is subject to change as additional information becomes available.
