The relationship between blocking antibody negative fetal arrest

Fetal arrest means that the fetus stops growing in the mother's uterus, mainly in the first three months, without any warning bleeding. The negative blocking antibody test is very unfamiliar to many women, but women who have suffered miscarriage are particularly familiar with it, because the negative blocking antibody test can lead to miscarriage. So what is the relationship between negative blocking antibodies and fetal arrest?

What is the correlation between negative blocking antibodies and fetal arrest?

A normal pregnant woman's blood cells contain a blocking antibody that inhibits the reaction of reticulocytes. Because they block the same antigen and stimulate reticulocytes, they produce migration inhibitory factors and are therefore called blocking antibodies. The test tube embryo is not likely to be considered a foreign object by the pregnant woman's immune system and attacked, leading to miscarriage. The test tube embryo that has not been hacked is the contribution of blocking antibodies, which are the antigens that protect the fetus. The negative blocking antibody can prevent the pregnant mother's immune system from attacking the test tube embryo and hindering its growth and development.

What causes the fetal stop?

Fetal arrest is the cessation of growth and development of the fetus in the uterus, which is unexpected for many mothers. The causes of fetal arrest include:

1. The fetus stops growing because of the woman’s own mental and work stress.

2. During pregnancy, an irregular lifestyle will cause the test tube embryo to stop growing and developing.

3. With the development of the times and the popularization of electronic devices, the radiation source for pregnant women is increasing.

4. Excessive exercise in early pregnancy.

Under normal circumstances, during pregnancy, there are professional tests for blocking antibodies. Only women who have had miscarriages need to be checked, not everyone needs to do it. If a woman is diagnosed with negative blocking antibodies during the test, she needs to go to the hospital for treatment immediately. Fetal arrest will lead to miscarriage, affect the health of expectant mothers, and even leave complications to the mother's body.
