The COVID-19 IgG & IgM  Rapid Test Device utilizes lateral flow technology that is used for the qualitative, differential detection of both anti-SARS-CoV-2 IgM and IgG antibodies. In general, antibodies can be detected 1-3 weeks after infection. This test is intended to screen patients for COVID-19 for recent or past infection. 


How accurate is COVID-19 IgG/IgM Rapid Test Device?


  • The COVID-19 IgG/IgM has been evaluated with the 113 blood samples obtained from patients exhibiting pneumonia or respiratory symptoms.
  • The sensitivity of the IgM test is 87.9% and specificity 100% when compared to RT-PCR.
  • The sensitivity of the IgG test is 97.2% during the convalescence period, and specificity is 100%.
