Free Examinations During Pregnancy

There are many free examination items for women during pregnancy, which need to be done at specific times. If the examination is overdue or advanced, there will be a large error in the examination data. During pregnancy, women need to undergo an examination to rule out fetal malformations. Is it too early to undergo the major anomaly screening at 23 weeks? The best time for the major anomaly screening is between 23 weeks and 16 weeks, so it can be done at 23 weeks.

1. Is it Better to Undergo the Major Anomaly Screening at 23 Weeks or 24 Weeks?

The best time for the major anomaly screening is between 23 weeks and 26 weeks, and it is generally recommended to do it around 24 weeks, as the amniotic fluid is the clearest at this time and the imaging results are the best. The major anomaly screening mainly checks whether the baby's development in the uterus is consistent with the gestational age, whether the fetus is healthy, whether there are malformations in the limbs, brain, and internal organs, as well as the condition of the amniotic fluid and umbilical cord.

2. Precautions for the Major Anomaly Screening

1. Make an advance appointment and choose the best time. The best time for the color Doppler ultrasound anomaly screening is around 18-24 weeks of pregnancy. At this gestational age, the fetus is of moderate size, and the ultrasonic imaging is clearer. Most malformations can be excluded during this time. Therefore, pregnant women need to make an advance appointment at the hospital to avoid missing the time. Too early or too late gestational age is not suitable for fetal malformation detection, but there may be some differences based on the actual examination time of the pregnant woman.

2. No need to fast or hold urine. Preparation for fasting or holding urine is not required for the anomaly screening. Pregnant women can undergo the fetal malformation screening at a regular hospital during the corresponding time. Half an hour before the anomaly color Doppler ultrasound, pregnant women can eat something and drink some water, which can increase fetal movement.

3. Pay attention to clothing. The color Doppler ultrasound examines the fetus in the uterus, so it is best for pregnant women to wear separate tops and bottoms before the examination to facilitate the inspection.

4. Relax appropriately. If the pregnant woman feels tense before the color Doppler ultrasound, she should relax and ease the tension to prevent the normal activities of the fetus from being affected by her tension and interfering with the normal detection results.
