New lab test clarifies the potential protective effects of COVID-19 antibodies

Knowing you have developed antibodies against the SARS-CoV-2 virus after recovering from COVID-19 doesn't tell you everything about your immunity. Scientists have developed a new lab testing procedure for the detection of antibodies against SARS-CoV-2 that gives results more quickly than existing assays and specifically identifies so-called 'neutralizing' antibodies.
