What was the ratio they gave you ? An the scan will be to check for soft markers that point to downs syndrome eg. Bowel ,facial feature (nasal bone) etc if this also is positive they may do an amnio which is a needle into the womb to see which gives a more accurate reading but does carry a 1% chance of misscarriage. Hope this helps if you need to talk just message m hope your ok x
They didn't give me a ratio... And thank you
I took the quad screen with my last pregnancy and it came back positive. I went for the ultrasound sound and my little boy was fine. The dates were wrong. The doctor went by my last menstrual cycle and it marked me at 19 weeks. Well I wasn't but 16 by the ultrasound. I didn't take the quad this time around.
