what is your point? If your doc

did not order those OB ultrasound then you probably would sue him/her for not ordering enough test to detect the polydactyly. In fact the perceived "failing to order approprite test" is among the top reasons primary care MDs getting sued -- and this drives healthcare cost higher and higher.

Good luck on your cooperation with you MD to exclude other things for your baby, as well as genetic consuling for your future children!

You are right that 健坛 is not a place to ask for health related help, unless you want to buy those magic water or stuff like that! :)
