How Does This Test Work?

This simple plasma/serum test detects circulating neutralizing antibodies against SARS CoV-2 that block the interaction between the receptor binding domain (RBD) of the viral spike glycoprotein with the ACE2 cell surface receptor. This test is suitable for all antibody isotypes making it an effective way to monitor vaccine response.

How long vaccine protection lasts, and how much vaccines protect against emerging COVID-19 variants, still is under investigation. Until more is known and vaccination coverage increases, some prevention measures will continue to be necessary for all people, regardless of vaccination status.
