Early prenatal diagnosis of genetic abnormality by chorion villus sampling

N Z Med J. 1990 Apr 11;103(887):157-8.


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.
