Went for my first u/s at 11 weeks they told me I was actually 10+6 and that they wouldn't be able to do the NT scan as the foetus needed to be bigger, so they rescheduled for 13+5 which was today. We couldn't have an appointment at 12 weeks as we got married and were on honeymoon. However, we were assured that a test at 13+5 would be no problem, so we didn't worry and turned up today for our scan.
Today 13+5 (according to dating scan) we were told that they couldn't do the NT combined test as it was too late and also due to position of the foetus. The good news is that the baby is looking good, all checks done show a healthy foetus. The bad news is that we are booked in for a quadruple scan in two weeks time which we were told today has only 65% accuracy of detecting Down's syndrome. This means that over a third of Down's pregnancies would remain undetected using this method of screening. Not good enough for me, I am 37 and my OH is 45 so the risk is real.
Therefore, we decided to book in at the Portland Hospital in London who I have an appointment with tomorrow morning to do the Harmony test which is over 99% accurate at detecting Down's. it's non-invasive and has no risk to mother or foetus. They charge £600 which is bad, but this also includes an ultrasound. When I rang them they said they will also do the NT scan for me tomorrow and the combined blood test (in addition to sending blood to California for the Harmony test) as they do the NT test until 14+1.
Whilst £600 is a lot of money, the consequences of a false negative are much more costly to us no matter how small the risk overall. We are effectively paying for peace of mind.
I don't understand the 'too late' comment at 13+5.. that was how far I was with my daughter at my first scan and I had the screening. Maybe it differs at different hospitals, or the position was more of an issue.
Hope you get your peace of mind
Edit: just seen that other hospital will do it to 14+1 crazy they're all different
So weird. I think all pregnancy websites say they can do it up until 13+6 but I guess it depends on what kind of machine each hospital has. Either way, my baby was laying in a bad position for them to see the nuchal fold so they used the wand (and me emptying my bladder) to coax the baby to turn into a good position and were able to get the shot.
