“Singclean” COVID-19 antibody Rapid Test Kit Colloidal Gold Method is a solid phase immunochromatographic assay for the rapid, qualitative and differential detection of IgG and IgM antibodies to Novel Coronavirus in human whole blood, serum or plasma. This test provides only a preliminary test result. Therefore, any reactive specimen with the COVID-19 IgG/IgM Test kit Colloidal Gold Method must be confirmed with alternative testing method(s) and clinical findings.
IgM and IgG are immunoglobulins produced by the immune system to provide protection against COVID-19 and can be detected in the serum, plasma or whole blood.
IgM: forms early in the immune response, normally appears 7 days of symptom onset.
IgG: appears later than IgM, IgG antibodies generally can be detected from 10 days of symptom onset and can last for months or even longer, remaining detectable in blood after the disease resolution.
