In my experiences probably 90% of women who found out what they were having had what they were told. I did look after one woman who told me she had 5 scans and was told she was having a girl each time and what do you know out popped a boy! She was so, so, so shocked. Had the nursery painted pink, pink clothes, pink everything!
Like the other girls have said, the sonographers tend to add the "it's impossible to ensure the absence of abnormalities" spiel either verbally or on the report (usually always on the report) to protect themselves from litigation - kinda like how the MO's have to go through all of the risks of a procedure with a patient prior to them signing the consent form. All about litigation!!!

Ryn, i can't believe they perform TOP's for clefts in the UK :eek:
