Who should take an antigen test?

  • People who have symptoms of COVID-19, especially within seven days of symptom onset. Please do not go to the library to obtain a test if you are symptomatic.
  • A close contact of someone with known or suspected COVID-19, who has no symptoms. Take the test as soon as you find out you are a close contact. If negative, do it again at 5-7 days after you last had contact with the person who has COVID-19 – or immediately if symptoms develop.
  • People who have no symptoms and participated in higher-risk activities in which they could not physically distance as needed (e.g., travel, attending large social or mass gatherings, or being in crowded indoor settings).
  • People who have no symptoms but are concerned and want a quick result (i.e.: before going to visit immunocompromised family). This screening for disease may allow for earlier detection of COVID-19 so that prompt public health intervention can be taken.
  • People with no symptoms who use antigen testing frequently to detect possible asymptomatic infection.
