As promised, I checked your biometric data in my system (PIA by Viewpoint). For a EDD on 10/29 GA is 39+2 wks on 10/24 (obviously). According to our reference curves by Snijider (Nicolaides group) BPD, CC, AC and FL were in the 45th, 45th, 25th and 40th percentile respectively. EFW calculated with Hadlock's formula (BPD, CC, AC, FL) was with 2961 grams at the 25h percentile according to Yudkins reference curve for 39+2 wks. The system gives you also the possibility to calculate EFW by an othe Hadlock's formula (FL,AC) resulting in 2891 grams and with Warsow's formula (BPD,AC) 2969 grams. As you see all quite consistent. Tedious numbers but it helps sometimes to redo all those calculations.

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.
