Help with nuchal translucency gest age is 12w+1d. crl is 52.2 nt is 0.9 fhr is 145bpm. crl also says 11w6d due date 12 28 14. what does this mean? low nuchal translucency means what? results ok?

No worries: The nuchal transulcency is measured to assess for the possibility of Down's syndrome or other chromosomal defects.Generally if measurement is greater than 3-4mm one of these defects is suspected.At 0.9 I'd say your baby has a low probability of this.CRLis right around where it should be for 12 weeks too.Sometimes the estimated gestational age based on size is slightly off,don't worry about this.
