ABSTRACT
In more severe cases, infection can cause pneumonia, severe acute respiratory syndrome, kidney failure and even death. [...]there is giant demand for the COVID-19 tests. In samples without infected, since there is no target gene amplification, no increase in fluorescence signal can be detected. [...]nucleic acid detection is actually to determine whether there is novel coronavirus nucleic acid in the sample by detecting the accumulation of fluorescent signals. According to the principle of double-antibody sandwich method, using two antigen-specific antibodies to recognize and bind to different epitopes of a target antigen can greatly reduce the probability of cross-reaction, thereby effectively improving its specificity [1]. Positive detection of IgG in blood can be used as an indicator of infection and previous infection [8]. [...]an increase of IgM antibody indicates a recent acute infection, and an increase of IgG antibody indicates a previous infection.
