Prenatal screening is done here as part of the 12 week scan, so there's no additional appointment. In my first pregnancy we had it done, then in my second we were living out here (we were in the UK before), and here they didn't offer it. Now they do, so were having it again. For us it's just a case of preparing ourselves for what might happen. It was a no brainier for us. They only do downs testing here though; bloods and nuchal fold measurements, but they don't combine them to get the more accurate result yet; it's all still early stages here
