Do I need to fast for Down syndrome screening?

Regular Down syndrome screening can effectively help us nip the disease in the bud. Once there is a problem with the normal value of Down syndrome screening, we must seize the time to solve it to avoid this situation causing us greater harm. However, there are many things we need to pay attention to when checking Down syndrome screening. Let us now understand whether fasting is required for Down syndrome screening.

Generally speaking, Down syndrome screening often uses a combined serological method to screen for Down syndrome. The process is to draw peripheral blood from the pregnant woman and then extract the serum from it. During this process, the pregnant woman does not have to fast. During the serum test, the concentrations of alpha-fetoprotein (AFP) and serum chorionic gonadotropin (HCG) in the mother's serum will be tested, and the "risk factor" will be calculated based on the pregnant woman's due date, age, gestational age at the time of blood draw, and weight. This can detect 60-70% of congenitally mentally retarded children. To achieve a "prophetic" purpose.

This test can also detect high-risk pregnant women for neural tube defects, trisomy 18 and trisomy 13. However, if the serum test is positive, amniotic fluid test is also needed to confirm the diagnosis.

It should be noted that you do not need to be on an empty stomach for the Down syndrome test, but you should also not eat too much for the test. If other tests requiring fasting are required on the same day, you can prepare as usual.

Do you need to fast for Down syndrome screening? The results of the test are different. Try not to eat in the morning when doing Down syndrome screening, otherwise it will affect our normal value test. At the same time, you should consult your doctor for other relevant precautions to ensure that the Down syndrome screening values ​​we get are in line with our own physical condition so that we can take appropriate countermeasures.
