SARS-CoV-2 IgG/IgM antibody Rapid Test Kit

1. The significance of a positive COVID-19 IgM antibody test

IgM antibodies are a sign of recent infection. Serum-specific antibodies will gradually develop 3 to 5 days after the onset of new coronavirus pneumonia, with IgM antibodies appearing first. Detection of such antibodies in the blood suggests recent infection with the novel coronavirus.

2. The significance of a positive COVID-19 IgG antibody test

IgG antibodies usually appear before IgM antibodies appear and exist in the body for a long time. They are commonly used indicators in epidemiological investigations and detection. A positive COVID-19 IgG antibody test indicates that there is an infection in the body, but it is unclear whether it is a current infection or a past infection.
