COVID-19 Serology (Antibody) Testing

Last updated on Saturday, Oct 10 2020, 09:23:59 AM

  • Serology testing looks for proteins in the blood called antibodies, which are produced by the body in response to the presence of a virus. Serology testing tells us whether someone was previously exposed to a virus and helps us understand the spread of a virus in a community and the state. Supplementing what we learn from diagnostic testing with antibody testing is important to understand how COVID-19 is spreading in the state and to support people and communities that are most vulnerable to COVID-19.
  • Serology testing does not tell us whether someone is immune to COVID-19. We are still learning whether the presence of antibodies protects someone from future infection, and if so, for how long. Therefore, it is important that people continue to take measures to prevent the spread of COVID-19.
  • Anyone can get a serology test through a primary care provider (PCP). Speak with a PCP to learn more about the testing procedure and the costs associated with serology testing.
