COVID-19 diagnostic strategy – Why antibody test matters?


The Antibody, also known as immunoglobulin, is a Y-shaped protein used by the immune system to identify foreign objects such as pathogenic bacteria and viruses.


Due to different function, the antibody divided into several isotype: IgA, IgD, IgE, IgG and IgM, in which IgG and IgM are the uppermost antibody invading pathogens. To target at these two isotypes in the COVID-19 antibody test leads to a comparably reliable testing result.


Antibody test can be used in hospital and healthcare center to recognize and follow the patients who are in the middle of recovering process, assisting to make a more accurate treatment strategy. Additionally, the antibody test is playing an important role during the infectiousness research.


Furthermore, as for the rapid test is easier and faster to perform and be able to deploy widely, antibody testing has significant potential value in prevention and controlling the pandemic outbreak as a more accessible and frequently use diagnostic method.

As a member of Bioperfectus COVID-19 diagnostic solution, our Novel Corona Virus (SARS-CoV-2) IgM/IgG Rapid Test Kit makes it possible for clinicians and individuals to detect COVID-19 IgM and IgG Antibody in one test with high sensitivity and specificity clinically proven in US, Russia and Turkey etc... Resulting in only 10-15 minutes allows communities to conduct population screening in a convenient and reliable way.
