RE: Covid29 Mass Testing Could End The Epidemic3 Apr 2020 00:03
'Serologic tests do have some drawbacks. The most common technique, called ELISA, involves exposing a blood sample to proteins that mimic the coronavirus’ spiky casing; if antibodies in the blood attack the protein, the sample changes color.
