This kit is based on the principle of gold label immunochromatographic test and uses capture method to detect the COVID-19 IgM antibody in the sample.
When the sample contains the COVID-19 IgM antibody, it forms a complex with the gold label antigen (COVID-19 recombinant antigen). The complex moves forward under the action of chromatography and combines with the coated antibody (Mouse anti-human IgM monoclonal antibody) at the T line to form a complex and develop color (T line), which is a positive result. When the sample does not contain the COVID-19 IgM antibody, no complex can be formed at the T line, and no red band appears, which is a negative result.
Regardless of whether the COVID-19 IgM antibody is contained in the sample, the gold label quality control antibody (rabbit IgG antibody) will bind with the coated antibody (goat anti-rabbit IgG antibody) at the C line to form a complex and develop color (C line).
Cassette: T-line coated with mouse anti-human IgM monoclonal antibody, gold label pad solid phase COVID-19 recombinant antigen, rabbit IgG antibody, C-line coated with goat anti-rabbit IgG antibody
Sample dilution: composed of 20 mM phosphate buffer solution (PBS)
Instructions must be read entirely before taking the test. Allow the test device controls to equilibrate to room temperature for 30 minutes (20℃-30℃) prior to testing. Do not open the inner packaging until ready, it must be used in one hour if opened (Humidity≤60%, Temp: 20℃-30℃). Please use immediately when the humidity＞60%.
