How accurate is amniocentesis?

Amniocentesis is an important means of prenatal examination and is widely used in clinical practice. It is basically suitable for older women over 35 years old or expectant mothers with genetic diseases. Amniocentesis is an invasive examination method. Because it is traumatic, many pregnant women are afraid of it. So let’s talk about the accuracy of amniocentesis?

Amniocentesis is an invasive test, and any invasive test has risks. Amniocentesis certainly has risks, but its overall risk rate, the risk of causing fetal miscarriage, generally does not exceed 1%. Moreover, in principle, large and medium-sized hospitals now require that amniocentesis must be performed under B-ultrasound. In other words, you have to watch it under the ultrasound, staying away from the baby and the placenta. Therefore, the possibility of causing harm to the fetus is even smaller. After amniocentesis, you just need to pay attention to preventing infection, paying attention to diet and nutrition.

Time: Amniocentesis can usually be performed between 16 and 20 weeks of pregnancy. Reason: ① There is more amniotic fluid during this period. When the pregnant woman undergoes this operation, it is not easy to be stabbed by the syringe that enters the amniotic fluid, which may affect the fetus. ②The amniotic fluid cells at this time are very active and conducive to cultivation. Even if serious abnormalities are detected in the fetus, induced abortion can be performed in time.

Through the above reading, we know that no more than 1% of pregnant women will suffer miscarriage during amniocentesis, which means that the accuracy rate of amniocentesis is over 99%, so expectant mothers should not be too nervous or worried. If amniocentesis is not necessary, then don't do it. If amniocentesis must be done, then be sure to follow the precautions before and after the amniocentesis. I believe that as long as you do this, it will not harm you and your baby.
