Overview
During infection, IgG and IgM are the most common antibody markers detected in blood. The IgM antibody is generally the first antibody detected during the preliminary stages of infection and is used as a marker of acute infection. As infection progresses, the concentration of IgM antibodies gradually decreases and disappears with the appearance of IgG antibodies. IgG antibodies usually exist in the body for a long time, even after the virus has been completely eliminated.
Data Figures

Figure 1. Indication of Positive Test Results Using the Human SARS-CoV-2 IgM/IgG Antibody Rapid Test Kit
[From left to right] Appearance of colored bands at the test line (M) and control line (C) indicate that the sample tested positive for anti-SARS-CoV-2 IgM antibody. Colored bands at the test line (G) and control line (C) indicate that the sample tested positive for anti-SARS-CoV-2 IgG antibody. Colored bands at both the test lines (G) and (M), and the control line (C) indicate that the sample tested positive for both anti-SARS-CoV-2 IgG and IgM antibodies.

Figure 2. Indication of Negative Test Results Using the Human SARS-CoV-2 IgM/IgG Antibody Rapid Test Kit
Development of a colored band only at the control line (C) indicates that the sample tested negative for both anti-SARS-CoV-2 IgG and IgM antibodies.

Figure 3. Indication of Invalid Test Results Using the Human SARS-CoV-2 IgM/IgG Antibody Rapid Test Kit
The absence of a colored band at the control line (C), irrespective of the presence or absence of colored bands at the test lines (M) and (G), indicates an invalid test result.
