How do you know you are at an increased risk? I just called my clinic and am likely going to have a CVS test...but I have had no other tests or screens to determine my increase of risk. Are people having standard blood screen/ultrasound around 11 weeks which tells you your risk? If you show no risk for DS (via blood screen/ultrasound)...does that mean CVS shouldn't even be a consideration? so confused. I am talking to a genetic counselor tomorrow.
