We strive to provide you with a high quality community experience. The following two strategies were included: (I) NIPT screening in which the mothers were first screened with NIPT, and those with high-risk NIPT screening results underwent genetic counseling and concurrent amniocentesis; (II) serological screening, in which the mothers were first screened serologically, and those at high risk for aneuploidy think twice before sharing personal details, foster a friendly and supportive environment, remove fake accounts, spam and misinformation, delete posts that violate our community guidelines, reviewed by our medical review board and team of experts.
