This chapter describes amniocentesis, chorionic villus sampling (CVS), and fetal blood sampling (FBS), which are the most frequently used invasive techniques to obtain this information. Most perinatal centers have the technical expertise to perform all of these procedures and to select the best method for each clinical scenario. However, certain conditions meriting specialized techniques may require referral to a fetal center.
