How much does it cost to do a Down syndrome screening test during pregnancy?

Down syndrome screening is a method of screening for fetal abnormalities. It is recommended to be tested at 16 weeks of pregnancy. Currently, some parts of the country offer free Down syndrome screening tests. You can consult the local neighborhood committee or hospital. If it is not free, the price is between 200-400, and you need to consult the hospital for the exact price.

Down syndrome screening is a comprehensive prenatal selection test for Down syndrome, commonly known as Down syndrome screening. This prenatal examination can determine whether the fetus is born with brain development disorder or central nervous system development disorder based on the concentrations of alpha-fetoprotein, human gonadotropin and free estriol in the pregnant woman's blood, and then combined with the mother's age, weight and pregnancy time.

The timing of Down syndrome screening is also very critical. The time for Down syndrome screening in early pregnancy is 11 to 13 weeks, and the best time is 12 weeks. The time for mid-pregnancy Down syndrome screening is between 14 and 20 weeks of pregnancy, and the best time to check is between 16 and 18 weeks. Whether it is early or late, it will affect the accuracy of the Down syndrome screening results. If a pregnant woman misses the time range for Down syndrome screening, there is no way to make up for it. She can only undergo amniocentesis and measure Down syndrome by drawing amniotic fluid.

Purpose of Down Screening Down screening refers to the screening which is a kind of examination method with special significance. It is aimed at special groups who do not have any corresponding symptom warning (such as all pregnant women). Through examination, key subjects who are most likely to suffer from a certain disease will be selected for subsequent diagnosis-related examinations.

What are the three key tests for Down syndrome screening?

Down syndrome screening is mainly for screening Down syndrome, that is, to check whether the baby will be a congenitally stupid Down syndrome baby, mainly checking the high level of alpha-fetoprotein, human chorionic gonadotropin, and free estriol.

Fetuses with Down syndrome are not exclusive to older pregnant women. Although older pregnant women over 35 years old are closely related to Down syndrome, the older they are, the greater the probability of giving birth to a child with Down syndrome. However, young women can also develop Down syndrome, and only 20% of Down syndrome occurs in older pregnant women, while the other 80% of Down syndrome babies are born in young pregnant women under 35 years old. Therefore, if only older pregnant women are tested, it will not be able to effectively prevent Down syndrome.

On the other hand, if all pregnant women undergo amniocentesis or CFS, not only will the cost be relatively high, but it will also increase the chance of miscarriage. Therefore, it is not necessary for all women to undergo amniocentesis or CFS. At present, the best way to prevent Down syndrome is: all pregnant women should undergo Down screening, and those who show high risk factors should undergo amniocentesis or CSF testing. Through amniocentesis or CSF testing, it can be determined whether the fetus's chromosomes are normal and whether it suffers from Down syndrome.
