Women need to undergo many tests during pregnancy, such as NT testing, non-invasive DNA testing, etc., and also need to undergo four-dimensional color ultrasound examination. When pregnant women undergo examinations, their biggest concern is that the results may be abnormal. So, if both NT and non-invasive have passed the four-dimensional test, will they pass?
When both NT and non-invasive methods have passed, there is a possibility that 4D ultrasound may not be able to pass. This is because NT testing and non-invasive DNA testing have little to do with 4D ultrasound, and the purpose of the examination is also different. Therefore, passing both NT and non-invasive tests does not necessarily mean that 4D ultrasound can pass.
Pregnant women who fail to pass 4D ultrasound are mostly due to the baby's lack of cooperation during the examination. Some babies like to sleep in their mother's womb and are unwilling to turn over. At this time, doctors cannot see the comprehensive situation of the baby. Four dimensional ultrasound during pregnancy is a very critical prenatal examination item, which is related to whether the child has defects. Therefore, doctors are very cautious and will not give approval when they cannot fully understand the condition of the fetus.
If abnormal conditions are found during four-dimensional ultrasound, it will definitely not pass. If doctors find that the fetus has intrauterine growth retardation, or has widened lateral ventricles, cleft lip, and renal pelvis separation, they usually ask the pregnant woman to undergo another examination next week to confirm the child's condition.
