O que significam os exames IgG e IgM?

New and more complete video on this subject:    • O que são IgG, IgM? (e IgA, IgE???) o que ...   Pregnant women often see the following result: Toxoplasmosis IgG - reactive. They are terrified, thinking that they have the disease! Immunoglobulins are markers of our immunity. There are several types: Immunoglobulin G - IgG; and the other immunoglobulins: IgA, IgE, IgM. IgG is the immunoglobulin of immunity. After we have come into contact with a disease or vaccine, it always circulates in our body, giving the result Reactive in the test. This means that if the body comes into contact with this disease again, it will make a rapid immune response, preventing us from getting sick. Therefore, having reactive IgG is GOOD!!! IgG is also passed on to the fetus, causing it to be born with some protection (passive vaccine). Immunoglobulins G remain active for 3 months in the baby. After that, the baby must be vaccinated to produce its own IgG. IgM, on the other hand, is the immunoglobulin of the active disease. The person who has this test reactive is being infected by the disease, because it is produced soon after contact, and remains active for a few months, being eliminated and replaced by IgG after the disease ends. IgM is the size of 5 IgGs, and because it is so large, it does not pass to the baby, and does not help in the defense of the fetus inside the womb. Having reactive IgM is bad during pregnancy, and this is the test that the pregnant woman should pay more attention to. IgA and IgE are not mentioned in the video, because they are not that important during pregnancy. IgA provides immunity to secretions (saliva, semen, vaginal content, breast milk) while IgE is associated with allergic processes.
