Immune System

If you’ve survived an infection of COVID-19, does that mean you’re now immune? The Mayo Clinic may have just discovered a way to find out.

Though research into immunity from novel coronavirus is still in its infancy, the Mayo Clinic might be ahead of the pack.

4. What the Coronavirus Immunity Test Does

Laboratory Tests

President of Mayo Clinic Laboratories, William Morice, II, M.D., Ph.D., explains how the Mayo Clinic’s test could help determine coronavirus immunity, plus help develop better coronavirus vaccines. “This new test provides us with incredibly important information about how effective a person’s antibodies are at neutralizing the virus. This will help us identify optimal convalescent plasma donors and ultimately help assess the efficacy of anti-SARS-CoV-2 vaccines.”

3. How the Coronavirus Immunity Test Works

Blood Test

The Mayo Clinic’s new COVID-19 immunity test determines whether or not a person has developed coronavirus-neutralizing antibodies. A neutralizing antibody works to block a virus from attaching to the receptors on a cell wall.

The novel coronavirus, also identified as SARS-CoV-2, has a spike glycoprotein coating that binds to healthy cells at their protein cell receptors. If a person has developed coronavirus immunity, the Mayo Clinic test would detect neutralizing antibodies that block the binding of coronavirus spike glycoprotein.
