Patient's question:
Did the results of the Down syndrome screening indicate trisomy 21 with a 1 in 210 risk? Is it necessary to undergo amniocentesis for a definitive diagnosis?Doctor's answer:
According to your test results, it indicates a high risk of Down syndrome screening, and further testing through amniocentesis is required. Trisomy 21 risk, also known as Down syndrome screening, is a prenatal screening test for Down syndrome. The purpose is to determine the risk level of the fetus having Down syndrome. If the Down syndrome screening results show a high risk of the fetus having Down syndrome, further confirmatory tests—amniocentesis and amniotic fluid cytology—should be conducted.
