Yes: Chorionic villus sampling (cvs) is done in the first trimester between 10-12 weeks. It has a slightly higher risk of miscarriage associated with it than an amniocentesis- which is usually done after 15 weeks- because it is performed earlier in the pregnancy. Blood tests and a nuchal translucency ultrasound are noninvasive genetic screening options.
