The U.S. FDA has granted emergency use authorization (EUA) to Genscript USA Inc. for its Cpass SARS-CoV-2 Neutralization Antibody Detection Kit, the first commercially available test to detect neutralizing antibodies in individuals previously infected with the novel coronavirus. The serology test measures levels of neutralizing antibodies in samples from patients recovering from COVID-19 as well as people vaccinated against the SARS-CoV-2 virus.

As more COVID-19 antibody testing becomes available, one question has been on everybody’s mind: Does the presence of antibodies to SARS-CoV-2, the virus responsible for the global pandemic, mean that people are protected from future infection? To that end, Genscript Biotech Corp., of Piscataway, N.J., has applied for emergency use authorization (EUA) with the U.S. FDA to market a test that specifically recognizes neutralizing antibodies to SARS-CoV-2.
