After pregnancy, women will have many troubles, such as regular prenatal check ups which can cause irritability. However, for the safety of the fetus, it is also necessary to undergo examinations. Down syndrome screening is an important part of prenatal screening. So, what diseases does Down syndrome screening mainly check for?
Down syndrome screening is a method of testing the risk level of Down syndrome, also known as Down syndrome, by drawing blood from pregnant women to determine if the fetus has trisomy 21, trisomy 18, trisomy 13 syndrome, and neural tube defects. Trisomy 21 refers to Down syndrome, also known as Down syndrome. Since the presence of chromosomal diseases in the fetus cannot be seen with the naked eye, the risk of chromosomal diseases can be estimated through Down syndrome screening. It is generally recommended that pregnant women undergo this examination around four months of pregnancy.
Down syndrome screening is a screening method that mainly predicts the risk level of fetal diseases. If it is low-risk, there is generally no need to further check for chromosomal issues; If it is a high-risk or critical risk, further non-invasive DNA testing or amniocentesis prenatal diagnosis is needed.
Down syndrome is the primary cause of intellectual disability. Children with Down syndrome have special facial features and various deformities, which can impose a significant burden on their families after birth. Therefore, regular check ups should be conducted during pregnancy. If diagnosed with Down syndrome, it is generally recommended to terminate the pregnancy.
