Nuchal translucency has been a marker for risk for aneuploidy, therefore, if karyotype is normal than forget about the NT. With that much discrepancy, I wonder how well the NT was performed? Was this from a center with much experience? Real easy to accidentally measure distance to the amnion. Too my knowledge suggesting adverse outcomes with increased NT and normal karyotype. Anyone, please correct me if I'm, wrong. NT is still a screening tool, and probably more effective to suggest decreased risk. As a screening tool, normal karyotype with abnormal NT is not unheard of.

The American Medical Association is no longer designating CME hours for AMA Category II CME credit. However, physicians themselves may self designate learning activities as Category II CME credit hours if they feel it is of sufficient educational merit and meets the formal definitions of continuing medical education. OBGYN.net believes these interaction in this forum meets these criteria. For further information see the AMA web site.
