SARS-CoV-2 lgG/lgM Antibody Test Detection

When body is infected with the new coronavirus, the specific protein of the virus stimulates the immune system and lead to an antibody response, the first antibody to appear is lgM, and then the lgG antibody. From the general process of acute infection, when the lgG antibody appears, the concentration will continue to increase, the lgM will continue to decrease or even disappear, and the lgG antibody will exist for a long time. The simultaneous dynamic monitoring of lgM and lgG antibody can be used in the auxiliary diagnosis of new coronavirus infection.
