Some pregnant women want to observe whether the fetal development in their abdomen is good during pregnancy, and at this time, they need to undergo a major screening test. So, how long does it take to make an appointment for major screening?
The so-called prenatal screening test is the well-known four-dimensional color ultrasound examination, which can be scheduled at 18 weeks of pregnancy. If it is in a larger hospital and requires a long queue, it is necessary to start the appointment more than a month in advance because if the appointment is made late, the best examination time may be missed. Generally speaking, this examination is best done around 22 to 24 weeks.
When doing this examination, there is no need to go without eating or hold urine, because there is no need to do a urine test. As long as the pregnant woman makes an appointment in advance and goes to the hospital on time for routine examinations, the screening for major abnormalities is a way to check whether the baby is developing normally. Before preparing for surgery, pregnant women can eat and drink a little more water half an hour in advance, as this can increase fetal movement and the results of the examination will be more accurate.
Moreover, the color ultrasound is used to check the intrauterine fetus, so it is better for pregnant mothers to wear separate clothes when they go to check, so that the check can be convenient, the mood can not be too nervous, and they must relax, so as not to interfere with the normal test results.
