Mine is this Friday and I have been told I will be out of pocket around $100. Like the others have said, it is optimal to have this U/S done between 12 and 14 weeks although the bloods have to be done at 10 weeks. I had my BT at 10 weeks and 1 day and was told I only had until 10 wks 4 days for the results to be accurate. I hope this helps. If you're worried about the cost and have two referrals, call them and see what they say. Good luck and HTH.
