AB  - Key  PointsPrenatal  diagnostic  procedures  allow  prenatal  detection  of  an  ever-expanding  list  of  fetal  abnormalities  by  obtaining  genetic,  biochemical,  and  physiologic  information  about  the  fetus.The  specific  procedure  selected  depends  upon  the  gestational  age  and  the  information  needed.Genetic  consultation  should  be  available  to  help  patients  choose  which  diagnostic  procedure  is  optimal  for  them.Earlier  prenatal  diagnostic  methods  have  become  increasingly  more  common  and  are  likely  to  increase  in  popularity.  The  most  studied  of  these  is  CVS.  Transcervical  and  transabdominal  techniques  are  equally  effective.Early  amniocentesis  is  not  recommended  now  that  compelling  evidence  regarding  its  disadvantages  has  been  published.Advances  in  molecular  techniques  have  led  to  a  declining  number  of  reasons  for  using  percutaneous  umbilical  blood  sampling.  It  is  now  rarely  the  procedure  chosen  for  determining  fetal  karyotype.Percutaneous  umbilical  blood  sampling  is  the  most  direct  method  of  evaluating  fetal  anemia  secondary  to  severe  Rho(D)  disease.The  majority  of  invasive  diagnostic  procedures  are  associated  with  low  rates  of  complications  commensurate  with  provider  skill  and  experience.
