Researchers looked at more than 3 million folks who had an antibody test for SARS-CoV-2. SARS-CoV-2 is the virus that will cause COVID-19.

They located that about eleven% of folks had SARS-CoV-2 antibodies. A lot more than 88% had a destructive test. And much less than 1% of checks were inconclusive.

The experts looked at who arrived down with COVID-19 soon after the test. They analyzed up to thirty times, 31–60 times, 61–90 times, and more than 90 times soon after.

About 3% to four% of folks with destructive antibody checks bought COVID-19 in every single time period of time. But people who had antibodies were much less likely to have COVID-19 as time went on. Only .3% of the folks with antibodies had a beneficial COVID-19 test more than 90 times soon after. Individuals without the need of antibodies were 10 instances more likely to get the disease.

The findings advise that folks who have a beneficial consequence from an antibody test could be at lessen risk for future an infection with SARS-CoV-2.

NIH’s Dr. Lynn Penberthy, who led the research team, describes that more concerns continue to will need to be answered. “We are even so inspired by this early discovering,” she states.
