Down's Syndrome: 1 in 1,174
Trisomy 13/18: less than 1 in 10,000
My age: 30
I'm honestly surprised at my DS odds. The thickness mesaured 1.28, there was a nasal bone present, so I was expecting a 1:5,000 or something. Maybe my age? I'm 30. I tried googling to find the "average" results, but they seemed to have a large variance...so I'm trying with a smaller sample size (you!)
What were your results?
