genetic screeningThe use of AMNIOCENTESIS or CHORIONIC VILLUS SAMPLING before birth to obtain fetal cells or a small portion of fetal tissue on which chromosomal, and to some extent gene, studies can be made. A number of serious genetic disorders can, in this way, be diagnosed at a very early stage after conception so that the option of terminating the pregnancy can be considered.
