Should I Get a COVID-19 Viral or Antibody Test?

The type of COVID-19 test, viral or antibody, will depend on whether you currently have COVID-19 symptoms. A wide range of symptoms – from mild to severe illness – may appear 2-14 days after exposure to the virus. A PCR test will tell you if you are currently infected with the virus, whereas the antibody test will tell you if you have been infected with the virus or have antibody response to your vaccine.
