What are the standard values ​​for the three pregnancy tests?

Pregnancy is a very important thing for both expectant mothers and a family. After becoming pregnant, women hope that their babies can be born safely and healthily. However, if they want to know whether the baby is healthy, they need regular prenatal check-ups. Generally speaking, if the three pregnancy standards are normal during pregnancy, the baby is usually very healthy. So what are the three pregnancy standard values?

What are the standard values ​​for the three pregnancy tests?

1. Down syndrome screening

Down syndrome screening is a very important type of prenatal examination for pregnant women. It is an important item to check whether the fetus has malformations. You should know that in China, the probability of a pregnant woman around 25 years old giving birth to a baby with Down syndrome is 1:1300. If the mother is over 35 years old, the probability of giving birth to a baby with Down syndrome will reach 1/365. Therefore, if you want to prevent fetal malformations, Down syndrome screening is an essential prenatal test. However, it is best for pregnant mothers to go to the hospital for relevant examinations between 16 and 18 weeks of pregnancy. Examinations too early or too late may affect their accuracy.

2. Four-dimensional color Doppler ultrasound

The Down syndrome screening we just mentioned is an important project for preventing fetal malformations, and four-dimensional color ultrasound is also a project for preventing fetal malformations. Four-dimensional color ultrasound is a clearer B-ultrasound technology. It can clearly see every part of the fetus's body and observe whether the fetus has congenital malformations. Generally, the best time to do a four-dimensional color ultrasound is between 20 and 25 weeks of pregnancy. If you do it too early, some parts of the baby's body may not be well developed, thus affecting the examination results. If you go too late and the examination reveals a deformed fetus, it will have a negative impact on the pregnant mother's health.

3. Sugar screening

The sugar screening is a prenatal checkup that every pregnant mother must do, and the purpose of this project is to confirm whether the pregnant woman has gestational diabetes. We all know that gestational diabetes will have adverse effects on both pregnant women and fetuses, and can easily affect the physical health of pregnant women and fetuses, so pregnant mothers must do sugar screening on time. However, pregnant mothers must pay attention to distinguish between sugar screening and Down syndrome screening. Although the names of these two examination items may be similar, the purposes of the examinations are completely different, so you must pay attention.

Pregnant mothers will also undergo various examinations during pregnancy. If these three examinations are normal during pregnancy, then congratulations, the baby in the belly may be very healthy.
