Question
When can I go to the hospital for a Down syndrome test during my pregnancy?
Answer
Early Down syndrome screening can be done between 11 weeks and 13 weeks and six days of pregnancy, while mid-pregnancy screening is available between 15 weeks and 20 weeks. It is advisable to undergo regular prenatal examinations even if the test results are normal. For pregnant women with high-risk test results, further non-invasive DNA testing or amniocentesis may be required to rule out fetal abnormalities. Additionally, a four-dimensional or two-dimensional ultrasound examination should be conducted between 22 to 26 weeks of pregnancy to rule out fetal anomalies.
