Biotime one of the top dogs at 100%
A blood test, Biotime's kit uses cartridges, absorbent paper, and other materials to detect IgM and IgG antibodies. After 10 minutes, the company says it displays results with red lines indicating previous coronavirus infection.
The test has been studied several times now. One by the National Cancer Institute said it had combined scores of 100% sensitivity and 96.2% specificity for both kinds of antibodies. It got emergency approval from the FDA on July 24.
