FDA Clears a ‘New Generation’ of Covid Antibody Test Designed to Tell How Well Someone is Protected Against the Virus



The FDA has authorized one of the first Covid-19 tests that measures the amount of neutralizing antibodies produced by the body’s immune system after exposure to the virus — a “new generation” of coronavirus test that is designed to tell how well someone is protected against infection. Unlike many previously authorized antibody tests that can tell if you’ve had the virus or not, the COVID-SeroKlir test measures your specific levels of Covid-19 neutralizing antibodies. The FDA has previously authorized some tests that estimate the level of antibodies, but not specifically for neutralizing antibodies. The agency cautioned that much remains unknown about the nature of Covid-19 neutralizing antibodies in humans and that a high level of antibodies does not necessarily guarantee immunity against the virus.
