How to Correctly Use COVID-19 IgM/IgG Test Kit (Colloidal Gold Method)

Date:Apr 01, 2020

IgM/IgG Antibody Test has been stated in China Diagnosis and Treatment Protocol for Novel Coronavirus Pneumonia (Trial Version 7) as an effective testing method and evidence for Confirmed cases. And this test is being widely used by China’s Centers for Disease Control and Prevention to combat infections during COVID-19 outbreak.


Compared with nucleic acid test, this test can greatly help shorten the detection time to 10-15 minutes and no special facilities needed.


COVID-19 IgM/IgG Test Kit (Colloidal Gold Method) uses the colloidal gold-based method to detect IgM/IgG, antibodies to the COVID-19 in human whole blood, serum and plasma instead of detecting virus.


The COVID-19 IgM/IgG Test Kit only works after enough and detectable antibodies are produced. It is recommended that antibody test should be performed 7 days after showing symptoms (the body may not produce antibodies within 7 days). Antibodies are not produced in that period of infection, and the result could be false negative.


COVID-19 IgM/IgG Test Kit is used as auxiliary diagnosis for patients infected with COVID-19 and should not be the final basis for diagnosis. It is ideal for detecting suspected patients identified as being negative in nucleic acid test. Antibody test in combination with other testing methods can help improve the detection rate.


The most important thing is that COVID-19 IgM/IgG Test Kit should be operated by healthcare workers. Use by non-healthcare professionals can lead to deviation in test results.


Together, we are sure to win this battle against COVID-19 soon!
