If the test results show negative IgM and IgG antibodies, there is no need to worry. If the IgM antibody is positive, it suggests recent infection, and it is recommended to wait until the IgG antibody is positive before preparing for pregnancy. If the IgM antibody is negative and the IgG antibody is positive, you can prepare for pregnancy without worrying. At this time, the body has already produced effective antibodies against these four viruses, so there will be no recent infections in a short period of time, and it will not jeopardize the healthy development of embryonic tissues. Eugenics four tests include rubella virus, cytomegalovirus, herpes simplex virus and toxoplasma gondii, and the test requires a blood test on an empty stomach, which can clarify whether the body is infected with the above four viruses. However, the infection of the four viruses does not necessarily lead to embryo malformation, especially in early pregnancy, the degree of damage to the embryo by the four viruses depends on the time of infection, the concentration of the virus in the body, and the potency of the antibody, and it is not desirable to use the results of the eugenics four tests to determine whether the fetus can continue to be pregnant or not. Therefore, the detection of rubella virus, cytomegalovirus, herpes simplex virus and toxoplasmosis in early pregnancy does not necessarily indicate that the child is malformed and needs to be terminated by abortion, but rather, it is necessary to consider all aspects of the examination.
