Excerpt: New technologies, such as measuring nuchal translucency (NT), have allowed for earlier, noninvasive screening for chromosomal abnormalities and, when combined with serum screening in the first trimester, have comparable detection rates as standard second-trimester screening.
First-trimester screening offers several potential advantages over second-trimester screening.
If results are positive, it allows women to take advantage of first-trimester prenatal diagnosis by chorionic villus sampling (CVS) at 10-12 weeks or second-trimester amniocentesis ( 15 weeks).
Ob-Gyns Offering Large-Scale Cystic Fibrosis Screening
Excerpt: In recent weeks, ob-gyns began to greatly expand the number of couples offered genetic screening for cystic fibrosis (CF) during preconception or prenatal care, thanks to tests made possible by genetic research.
ACOG now recommends that ob-gyns make DNA screening for cystic fibrosis available to all couples seeking preconception or prenatal care - not just those with a personal or family history of carrying the CF gene, as previously recommended.
Testing will be made available to all couples, whatever their risk for carrying the CF gene, through information brochures on CF given to couples seeking preconception or prenatal care.
