HelloCustomer

All pregnancies are routinely screened for Down syndrome using blood tests & ultrasound. The risk of Downs syndrome in the baby depends on results of thses tests & mothers age.The ultrasound screening measures translucency of the skin folds t athe back of the neck.
The combination of blood tests & ultrasound screening has a detection rate of 95%. There is a 5 % rate falsely positive result.

If these screening tests all come positive, then they would do chromosomal analysis of the fetus by amniocentesis or chorionic villus sampling. Amniocentesis is examination of fluid that surronds the fetus & contains some floating fetal cells. Chorionic villus sampling is sampling the placenta for fetal cells.

So the botXXXXX XXXXXne is you need to wait for the further screening tests to know the exact risk. They will give a quantitative estimate of down syndrome risk based on the test results & your age.
