I've received a copy of a letter that my obstetrician has sent to my GP mentioning a diagnosis of Trisomy 21 and AVSD. We knew about the AVSD (hole in the heart) but when I looked up Trisomy 21, it means Downs Syndrome. We didn't have amnio or the other test to confirm Downs as the risk of miscarriage was too great (this is an IVF baby and too precious to take the risk) and a 4D scan shows no facial characteristics of Downs, so how on earth could they make a diagnosis like that? Has anyone else had such a diagnosis? As it's the weekend, I can't speak to anyone at the hospital but I'm hoping it's either a mistake or it means something else. Don't get me wrong, this baby will be loved and doted upon regardless, but I'm just daffled that they can diagnose something which hasn't been proven.
