This kit is used for the qualitative detection of SARS-CoV-2 IgM and IgG antibodies in
human serum, plasma, and whole blood samples in vitro. It is only used as a supplementary
detection indicator for suspected cases of negative new-type coronavirus nucleic acid detection or
for nucleic acid detection in suspected case diagnosis. The combined use of the tests cannot be
used as a basis for the diagnosis and exclusion of pneumonitis caused by SARS-CoV-2 infection,
and it is not suitable for screening in the general population.
This kit is used to detect SARS-CoV-2 IgM and IgG antibodies in human serum, plasma or
whole blood, based on the principle of colloidal gold immunochromatography. If the sample tested
contains SARS-CoV-2 IgM or IgG antibody, the antibodies will bind to the antigens conjugated
colloidal gold nanoparticles, and then captured by the secondary antibodies in detection zone M
(M) or detection zone G (G) to form one or two red Lines which can be recognized by naked eyes,
indicating positive results. The result is negative if no red reaction line appeared in any detection
area. Under normal test conditions, the quality control line (C) should be colored to indicate that
the test is valid.
