COVID-19 IgG/IgM 2.0 Rapid Test

The COVID-19 IgG/IgM strip is for detection of IgG and IgM antibodies to COVID-19 virus. Anti-human IgG and anti-ligand are separately coated in the test line region 1 and region 2. During testing, the specimen reacts with COVID-19 antigen-coated particles in the test strip. The mixture then migrates upward on the membrane chromatographically by capillary action and reacts with the anti-human IgG and the ligand anti-human IgM. COVID-19 IgG or IgM antibodies, if present in the specimen, reacts with the anti-human IgG in region 1 or the ligand anti-human IgM. The complex is captured and forming a colored line in the Test line region 1 or 2.

According to Guidelines of COVID-19 Diagnosis and Treatment from China Ministry of Health, primary COVID-19 infection is characterized by the presence of detectable IgM antibodies 3-5 days after the onset of infection. 

Secondary COVID-19 infection is characterized by the elevation of COVID-19-specific IgG. In the majority of the cases, this is accompanied by elevated levels of IgM. 

The COVID-19 IgG/IgM part has been compared with some clinical COVID-19 patients confirmed by PCR and CT, demonstrating sensitivity of 70% for IgM in primary infection and >99.0% for IgG in secondary infection.
