The charging standards for anomaly screening vary from place to place, mainly depending on whether the expectant mother chooses 2D color ultrasound, 3D color ultrasound, or 4D color ultrasound. The price of 2D color ultrasound is around 130 yuan, while the price of 3D color ultrasound generally ranges from 250 to 400 yuan, and the price of 4D color ultrasound varies between 300 and 500 yuan. It mainly depends on the local consumption level and the grade of the hospital. Precautions for anomaly screening:

1. Inspection time: It is suitable for inspection within 24-28 weeks of pregnancy. Beyond this period, the fetal facial features, limbs, heart, and other structures may not be observed completely or clearly. If there is extremely little or no amniotic fluid, these structures of the fetus may also not be displayed clearly.
2. Instrumentation: High-resolution color Doppler flow imaging instruments should be used for inspection. General black-and-white B-ultrasound for 4D color ultrasound only requires the above-mentioned routine ultrasound examination content, and generally does not require detailed systematic fetal anomaly ultrasound examination using black-and-white B-ultrasound.
3. Advance appointment: It is most suitable to undergo anomaly screening around 24-28 weeks of pregnancy, so expectant mothers need to make advance appointments at the hospital to avoid missing the time. Too early or too late gestational weeks are not suitable for fetal anomaly detection. However, there may be differences based on the actual inspection time of the expectant mother.
4. No fasting or holding urine: Preparation for fasting or holding urine is not required for anomaly screening. As long as the pregnant woman undergoes the inspection at a regular hospital during the inspection time for 4D color ultrasound, fetal anomaly screening can be performed. Half an hour before the anomaly screening ultrasound, the expectant mother can eat something and drink some water, which can increase fetal movement.
