Patient's question:
16-weekONTD risk value is 1220, high risk is 1270, the doctor recommended amniocentesis but said there is a risk of miscarriage and infection. I had a premature birth three years ago, and I have already scheduled a 2D color Doppler ultrasound to be done at 23 weeks. Can the 2D color Doppler ultrasound confirm it, or do I need to have a 4D ultrasound or must have an amniocentesis.Doctor's answer:
A Down syndrome screening is a test that involves extracting pregnant women's serum to examine the concentration of alpha-fetoprotein and human chorionic gonadotropin in the maternal serum. By combining the pregnant woman's due date, age, weight, and gestational age at the time of blood collection, it estimates the risk coefficient of giving birth to a child with Down syndrome. Children with Down syndrome have severe intellectual disabilities, cannot be self-sufficient in life, and often suffer from complex cardiovascular diseases, requiring long-term care from family members. This can impose significant emotional and financial burdens on the family.Your Down syndrome screening indicates a high risk, suggesting a higher likelihood of conceiving a child with Down syndrome. It is necessary to undergo amniocentesis and fetal chromosome examination to determine whether the child has Down syndrome. A 2D color ultrasound examination cannot replace amniocentesis.
