A new blood test may help identify individuals whose plasma contains antibodies to SARS-CoV-2 virus that causes COVID-19, and could potentially be used to treat other patients, scientists said NEW YORK : A new blood test may help identify individuals whose plasma contains antibodies to SARS-CoV-2 virus that causes COVID-19, and could potentially be used to treat other patients, scientists said on Tuesday.
Tests that detect the presence of SARS-CoV-2 RNA are widely used to diagnose COVID-19, according to the researchers from Icahn School of Medicine at Mount Sinai in the US.
However, assays that can measure the presence of antibodies to the virus may potentially help determine the rate of infection in a population.
