Prenatal screening critical risk

During the entire pregnancy process, expectant mothers have to go through many simple and complex prenatal examinations. The purposes of various prenatal examinations are different. This is to more comprehensively understand the health and development of the baby in the belly. However, not every expectant mother is so lucky that she can pass the prenatal check-up successfully every time. Today we need to talk about what to do if you have critical risk of prenatal diagnosis during mid-pregnancy?

What to do if you have critical risk of prenatal diagnosis during mid-pregnancy

1. Don’t be too anxious

Some pregnant mothers are very anxious when they see the result. They want to have a test immediately to know the result and can't wait for a while. When the doctor in the prenatal examination department tells her that it is best to wait for the B-ultrasound results to come out and make a comprehensive analysis before making a decision, she seems to be very anxious.

2. Don’t be too numb

Other pregnant mothers held an indifferent attitude and said, "I think many mothers around me had high-risk amniocentesis tests and the results were all normal. My critical value is abnormal, so it should be fine."

3. Seek specific guidance from technical professionals

A borderline risk screening result usually indicates that the baby is at higher risk of having a common chromosomal abnormality than other fetuses, and it also indicates that the fetus may have other rare chromosomal abnormalities that cannot be identified through general prenatal examinations without further testing. Therefore, if you encounter this situation, you must seek advice from professional staff.

4. Wait

When encountering this situation, the doctor in the prenatal examination department will recommend that you wait patiently for the results of the fetal ultrasound screening. If the ultrasound data show that the fetal structure is abnormal (that is, the appearance is incomplete), the risk of the fetus having chromosomal abnormalities is very high; if the fetal B-ultrasound shows that there is no obvious abnormality in appearance, relatives and pregnant women may have the opportunity to choose invasive or minimally invasive methods to further screen the fetus for chromosomal abnormalities.

Prenatal diagnosis of high-risk diagnosis methods

1. Villus aspiration biopsy: Birth defects such as Down syndrome, familial Tay-Sachs disease, and cystic fibrosis can be diagnosed through villus aspiration biopsy.

2. Amniocentesis: This invasive test carries the risk of amniotic fluid leakage, infection, and miscarriage for pregnant women, but the risk is very low, only about 0.1%. In addition, if you miss the appropriate pregnancy week, you can no longer do it.

3. Minimally invasive DNA gene testing: Through B-ultrasound and collecting 5ml of peripheral blood from the pregnant woman, mineral acid DNA is obtained, and analysis is performed to test whether the fetal chromosomes are normal, with an accuracy of 99%. It has the characteristics of non-invasiveness, short cycle time, no risk of miscarriage, and high accuracy, and provides a new option for pregnant women who do not accept or miss invasive tests.

When finding abnormalities in the fetus during the prenatal check-up, pregnant mothers should remember not to panic, because the mother's mood will be directly transmitted to the fetus, so that the fetus will also be anxious and negative emotions will increase, which is not good for the health of the fetus. It is okay if the fetus has abnormal growth and development. As long as you seek medical advice and take intervention measures in time, the fetus can grow and develop normally!
