title: Early prenatal diagnosis of genetic abnormality by chorion villus sampling.
abstract: We describe a series of 100 cases of prenatal genetic diagnosis using the technique of chorion villus sampling. The advantage of chorion villus sampling in terms of earlier diagnosis, and its disadvantage of a higher incidence of false results, compared with amniocentesis, are noted. The comparative risks for pregnancy loss are discussed.
