What is this test?
The COVID-19 S-RBD neutralizing antibody test detects antibodies against the SARS-CoV-2 spike protein receptor-binding domain (S-RBD) in the blood. It helps evaluate the humoral immune response following vaccination or a past infection. The test is not intended to diagnose an acute COVID-19 infection.
