title: Cost-effectiveness ratio of chorionic villi biopsy for the prenatal diagnosis of chromosomal aberrations as compared with amniocentesis.
abstract: The observed cost of amniocentesis for the prenatal diagnosis of chromosomal aberrations in pregnancies at risk because of advanced maternal age was compared with the estimated cost of chorionic villi biopsy (CVB). The cost of CVB was estimated to be 22% less than that of amniocentesis when the cost of the sampling procedure, the laboratory charges and the cost of spontaneous and therapeutic abortions were considered.
