Many pregnant women have positive giant cell igm

Pregnant mothers probably know that the harm of rubella virus to the fetus is very serious. The fetal malformation rate, mortality rate and complications are all shocking. If the rubella virus igm test is positive, is it necessary to abandon the fetus? How can a small life be simple? The editor has found some information from various channels for reference only, hoping to be of some help to pregnant mothers in need.

Somatic virus infection IgM-positive can be divided into primary infection and recurrent infection. The fetal malformation rate of primary infection is relatively high, reaching 30~40%. If primary giant cell infection occurs in the early stages of pregnancy (within three months), the impact on the fetus will be relatively large. The harm caused by recurrent infection is much smaller, and the impact on the fetus in early pregnancy is very small, with the probability within 1%.

So how do we know whether it is a primary infection or a recurrent infection? We must do an IgG, IgM, and DNA test, refer to the following:

1. IgG positive, Igm negative: previously infected with the virus and produced antibodies, but not recently infected with the virus. A primary infection has occurred long ago, and there has been no recurrent infection recently.

2. IgG positive, Igm positive: previously infected with the virus and recently infected with the virus.

3. GG is negative and IGM is positive: the patient has not been infected with the virus before, but was infected recently. This is basically a primary infection.

The second situation is more common, because many friends did not check for rubella virus before pregnancy, and all were discovered during pregnancy. It is impossible to distinguish whether it is a primary infection or a recurrent infection. In this case, the doctor cannot distinguish which one it is.

During pregnancy, if you have no clinical symptoms of primary infection, the possibility of recurrent infection is higher and further observation is required during the subsequent process. B-ultrasound examination is performed to check for abnormalities. At 20 weeks, it is recommended to do umbilical cord blood test or amniocentesis, etc. These are all very accurate ways to rule out fetal abnormalities.
