IgG antibodies without IgM means a past mono infection. People with very low immunoglobulin levels, especially IgA, IgG, and IgM, have a higher chance of developing an infection. A very small number of people cannot make IgA and have a higher chance of developing a potentially life-threatening reaction to a blood transfusion. Positive IgM and positive IgG antibodies indicates you may be in either the active phase of infection or the late or recovery stages of infection.

There is still a chance that the antibodies indicate past infection due to other coronaviruses. These other coronaviruses cause the common cold. There is also a small chance that a positive result is incorrect (false positive). The presence of IgM (with or without IgG) suggests that the infection happened within the last few weeks. Antibodies are glycoproteins, termed as immunoglobulins (Igs), which are produced in response to an immune reaction.IgM is Positive and IgG is Negative . This test result indicates that the immune system is actively producing antibodies to a recent infection (Fig. 3). The subject should immediately isolate from healthy individuals and seek further medical advice if symptoms develop. This subject can likely spread disease to others, even when asymptomatic.False positive results may occur due to cross-reactivity from pre-existing antibodies or other possible causes.
