The Coronavirus can be screened and diagnosed by measuring the IgG & IgM antibodies in human blood, serum, or plasma. The Antibody COVID-19 (SARS-CoV-2) Test Kit is one of the few products on the market designed for both IgG and IgM rapid diagnosis. The effectiveness of this test kit has been verified by both U.S. and foreign virologists as well as by the FDA. This COVID-19 test kit is currently being used in more than 20 countries, covering Asia, Europe, Australia, North America, South America, and Africa.
