The full name of IgG is Immunoglobulin G. In the report of the eugenics test three items are positive for IgG, while IgM is negative, there is no need to do any treatment. IgG is a protective antibody and being positive means that the woman is currently resistant to these types of microorganisms. It is due to previous exposure to these microorganisms and has developed an immune function against them, which means that when exposed to these pathogenic microorganisms in the future, the body itself will have a protective stress response and will basically not be affected by it. IgG has antibody activity against viruses, bacteria and parasites, etc. It is also the only immunoglobulin that can pass through the placenta, allowing the newborn to acquire immune antibodies through natural passive immunization. So don’t be nervous about just checking positive for IgG, as long as there is no positive IgM.
