Does not doing Down syndrome screening have any impact?

Young pregnant women under 34 years old should undergo Down syndrome screening. The test can be carried out within 15 to 20 weeks of pregnancy, preferably between 16 and 18 weeks.

Pregnant women who are over 34 years old, women with Down syndrome in their family, and women who have given birth to Down syndrome patients are already at high risk, so they do not need to undergo Down screening tests, but should undergo amniocentesis or CFS in a timely manner.

The best time to do Down syndrome screening is 14-20 weeks, but nowadays, even if you go to the hospital outpatient department, they won’t do it. If you are really worried, it is recommended to go to the hospital for amniocentesis.

Down screening refers to a special testing method that is aimed at special groups that do not have 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 with a higher risk of having fetuses with congenital idiocy, tongue-throwing dementia, etc. are screened out through screening, and the next step of diagnosis and related examinations are carried out. If the fetus is finally diagnosed with these congenital diseases, there is currently no effective treatment, and the best way is to terminate the pregnancy.
