What to do if you fail the Down syndrome screening

When a woman is pregnant, she must do various pregnancy checkups on time. These checks are very important, such as B-ultrasound, Down's syndrome screening, etc. Some pregnant women will fail the Down syndrome screening, which will make them very worried. So, what should I do if I fail the Down syndrome screening?

If the Down syndrome screening result is unqualified, you should also consider the situation. If the result is not high-risk or critical risk, you don’t need to worry too much. Although this is not 100% safe, you just need to pay attention during the subsequent prenatal check-up.

If the test results are high risk, further diagnosis should be done, such as amniocentesis, chorionic villus sampling or umbilical cord blood puncture. Which test to choose should be based on the number of weeks of pregnancy. If the test data of Down screening shows a marginal risk, it is not a significant abnormality, so it is not a high risk. In this case, pregnant women can undergo a minimally invasive DNA test.

Many pregnant women who have not passed the sugar screening are very worried. In fact, pregnant women need to calm down first, because high-risk does not mean 100% that they will get sick. At this time, they should do the next step of inspection immediately. If a pregnant woman undergoes amniocentesis or chorionic villus sampling, there are some risks, and there is about a 2% chance of experiencing adverse symptoms such as vaginal bleeding and uterine contractions.

Screening is a special testing method. It is aimed at special groups without any corresponding disease signs (such as all pregnant women). Through testing, key subjects who are most likely to suffer from a certain disease are selected for subsequent diagnosis-related examinations. One thing that needs to be established is that the purpose of screening is not to diagnose a certain disease, but to select people who are very likely to have a certain disease.

The current screening and diagnosis of Down syndrome, trisomy 18 and congenital neural tube defects is a systematic approach. First, for all pregnant women, those whose fetuses are at higher risk of suffering from the above three diseases are screened out through screening, and then the next step of diagnosis-related examinations is carried out. If the fetus is finally diagnosed with this congenital disease, the pregnant woman can make her own decision whether to become pregnant again.

The above-mentioned diseases usually use the same screening method, that is, based on your age, weight, AFP and β-HCG levels in your venous blood, combined with some other conditions (such as whether you smoke or drink alcohol, etc.), the risk of your fetus suffering from the above three congenital diseases is calculated.
