What tests should pregnant women take at 20 weeks?

You can go to the hospital for a prenatal check-up when you are 20 weeks pregnant. At this time, the content of the check-up is relatively large, there are routine check-ups and key check-ups. The key check-ups are mainly to rule out fetal malformations. When doing the prenatal check-up, you should understand some precautions, especially when going to some large hospitals. You should pay attention to arranging your time reasonably and do some preparation. Let's take a look at this aspect.

What tests should pregnant women take at 20 weeks?

1. Routine prenatal examination items:

The third prenatal check-up is at 20 weeks of pregnancy. Routine examinations will include blood pressure, weight, blood routine, urine routine, abdominal circumference, uterine height, and fetal heart rate. Through these examinations, the doctor can get a general understanding of the physical condition of the pregnant woman, see if there are any abnormalities, whether the fetus is developing at a normal rate, etc.

2. Key prenatal examination items: B-ultrasound (deformity screening)

Necessity of B-ultrasound (for fetal anomaly screening): B-ultrasound examination is arranged in the second trimester because there is relatively more amniotic fluid in the uterus at this time, the fetus is of moderate size, and there is a larger space for movement in the uterus. For B-ultrasound examination, there is better contrast, and the various organs of the fetus can be clearly seen. More obvious malformations, such as congenital heart disease, anencephaly, hydrocephalus, spina bifida, abdominal wall defect, short limbs, polycystic kidney disease, and gastrointestinal atresia are easy to detect. If necessary, timely treatment or termination of pregnancy can be carried out.

Prenatal check-up precautions

1. Pay attention to your dress. Color Doppler ultrasound examines the fetus in the uterus, so before going for the examination, it is best for the expectant mother to wear separate tops and bottoms to make it easier for the doctor to examine her.

2. Relax appropriately. If a pregnant woman is nervous before having a color ultrasound, she should relax appropriately to relieve the tension to prevent her nervousness from affecting the normal activities of the fetus and interfering with the normal test results.

3. No need to fast or hold urine. There is no need to fast or hold urine for fetal malformation screening. As long as the pregnant woman goes to a regular hospital for examination within the examination time of four-dimensional color ultrasound, fetal malformation screening can be performed. Pregnant women can eat something and drink some water half an hour before doing the color Doppler ultrasound to increase fetal movement.

4. The next prenatal check-up will be conducted at the 24th week of pregnancy. The next prenatal check-up will require a sugar screening. Expectant mothers should remember to reduce the intake of starch and sugar in the two weeks before the examination.

Therefore, pregnant mothers must not be lazy during pregnancy. It is very necessary to go to the hospital for regular prenatal check-ups, and the results of the examinations must be properly recorded for later follow-up needs. In addition, before and after the prenatal check-up, pregnant mothers should pay attention to adjusting their work and rest schedule, maintaining a good attitude, and adjusting their diet to make the examination results more effective.
