Hi. I am actually at the RAH in Paisley but wondering how long the NT tests are taking right now. I am 3 weeks since my bloods and the scan and still not heard a thing. I am 41 so worried about it as higher risk for chromosomal abnormalities etc. and can't believe it is taking so long. They said it might be 4 weeks! I will be 17 weeks when I get the results which is very worrying.
