The Biotime SARS-CoV-2 IgG/IgM Rapid Qualitative Test Kit is intended to detect SARS-CoV-2 IGg and IgM antibody in human serum, plasma or whole blood by colloidal gold method. 


Immunoglobulin M (IgM), which is found mainly in the blood and lymph fluid, is the first antibody to appear in the response to initial exposure to a new infection. IgM is with high specificity and high sensitivity to 2019-Novel Coronavirus(SARS-CoV-2), which has significant value in early detecting 2019-Novel Cornavirus(SARS-CoV-2).  Immunoglobulin G (IgG), the most abundant type of antibody, is found in blood and protects against viral and bacterial infections. IgG appears later than IgM when infected with SARS-CoV-2, but it can persist in the blood for several months, so positive IgG may indicate patients were ever infected with virus.
