Northwestern develops coronavirus antibody test using single drop of blood
Northwestern University researchers have put forth a coronavirus antibody test that they say can be completed using only a single drop of dried blood from a finger prick. The test, which is specifically designed to search for SARS-CoV-2 antibodies IgM and IgG, will help in “evaluating how effective policies such as social distancing or closing schools and restaurants are working to prevent viral transmission,” as well as eliminate the need for a clinical setting, according to the team’s lead author.
Thomas McDade, a biological anthropologist, said the test will also help in “ascertaining the true prevalence and mortality rate of infection.”
The researchers developed two dried blood spot-based protocols to test for SARS-CoV-2 IgG antibodies. Those who are tested will be sent a finger prick to illicit a small sample of blood, which is then …continued .
