Dépister la trisomie 21 pendant la grossesse - La Maison Des Maternelles

This is one of the important stages of pregnancy. Before the end of the first trimester, every pregnant woman can, if she wishes, be screened for Down syndrome. This includes the famous ultrasound to measure the thickness of the nuchal fold of the fetus, the blood test known as "serum markers"... and depending on the results, amniocentesis or chorionic villus sampling.
