COVID-19 IgG/IgM Antibodies Rapid Test

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%.
What is the significance of the various test results?
  • IgM negative, IgG negative: Patient not exposed or too early.
  • A medical professional should observe symptoms and epidemiology of patients.
  • Retesting should be considered if symptoms appear or persist.
  • IgM positive, IgG positive/negative: Acute or recent infection.
  • IgM negative, IgG positive: Previous, distant infection.
