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.
