Scope Of Application

COVID-19 IgG/IgM Rapid Test Cassette is for the detection of IgG/IgM in human serum, plasma or whole blood. It cannot be used as the basis for the diagnosis detection and of exclusion of COVID-19.

Intended Use

This kit is suitable for in-vitro qualitative detection of antibodies against novel coronavirus disease (COVID-19) in suspected/confirmed patients, serum/ whole blood samples. Compared with nucleic acid detection, there is much less false negative test result and the possibility of false positive test result is also very low. It can be used as a supplementary diagnostic tool for those with novel coronavirus nucleic acid test negative and suspected cases, or as a collaborative test of nucleic acid test in diagnosis of suspected cases, or as a confirmation in diagnosis and treatment.


  • Can qualitatively detect IgM and IgG SARS-CoV-2 specific antibodies simultaneously.
  • Commercially available.
  • Easy to perform.
  • Single use, rapid test.
  • Very short time to get test result.
  • Long-term stability at room temperature.
  • Relatively inexpensive to make.
Detection Principle

The kit uses colloidal gold immunochromatography and indirect immune capture principle of comprehensive detection technology to detect IgG/IgM of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) in human serum, plasma and whole blood. During detection, the colloidal gold labeled recombinant antigens bind to the SARS-CoV-2 antibodies in the sample to form immune complexes. The immune complexes move forward along the cassette by chromatography. The IgM in the immune complexes will be captured by the pre-coated anti-human IgM on the test zone, condense the color to form the reaction line M. The IgG in the immune complexes will be captured by pre-coated anti-human IgG on the test zone, condense the color to form the reaction line G. The colloidal gold-labeled chicken IgY antibodies are combined with the pre-coated goat anti-chicken IgY antibodies on the quality control line to form the quality control line C.
