測定原理：We have materials for development of COVID-19 IgG/IgM Rapid Test. It applies the GICA(Gold Immunochromatography) method for the detection of IgG and IgM specific to SARS-CoV-2 (2019-nCoV) in human bilogical fluids. It consists of two test lines, an IgG line and an IgM line, and a control line. The mouse anti-human IgG monoclonal is pre-coated in IgG test line region while the mouse anti-human IgM monoclonal is pre-coated in IgM test line region. And the goat anti-chicken IgY polyclonal is pre-coated in the control line region. During testing, the sample reacts with SARS-CoV-2 (2019-nCoV) antigen-coated particles in the test cassette. The mixture then migrates upward on the membrane chromatographically by capillary action and reacts with the anti-human IgG in IgG test line region. If the sample contains IgG antibodies to SARS-CoV-2 (2019-nCoV), a colored line will appear in IgG test line region. In the same way, if the sample contains IgM antibodies to SARS-CoV-2 (2019-nCoV), a colored line will appear in IgM test line region. And if the tested sample does not contain antibodies specific to SARS-CoV-2 (2019-nCoV), no colored line will appear in either of the two test line regions, which indicates a negative result.To serve as a procedural control, a colored line will always appear in the control line region, indicating that the proper volume of sample has been added and membrane wicking has occurred.
