AB It  is  possible  to  diagnose  in  utero,  before  the  middle  of  the  second  trimester,  mendelian  disorders  for  which  a  gene  is  associated,  all  chromosome  aberrations,  and  a  number  of  congenital  malformations  that  are  not  mendelian.  The  first  step  toward  prenatal  diagnosis  is  taken  when  the  expecting  couple,  the  primary  care  provider,  or  the  obstetrician  thinks  of  the  need  for  it.  However,  even  for  the  most  common  indication  for  such  service—advanced  maternal  age—less  than  50%  of  all  women  35  years  and  older  in  the  United  States  are  offered  prenatal  testing.
