Amniocentesis or chorionic villus sampling is necessary to conclusively diagnose the majority of genetic disorders, with amniocentesis being the gold-standard procedure after 15 weeks' gestation. [3] Transabdominal chorionic villus sampling is an alternative to amniocentesis if genetic diagnostic testing is to be performed in the first ...
The development of amniocentesis in 1952, fetal blood sampling during labor in the early 1960s, more precise fetal heart monitoring in 1968, and real-time ultrasound in 1971 resulted in early intervention and lower mortality rates. [2]
Testing Women, Testing the Fetus by Rayna Rapp is a book, published in 1999, about analysis of the social repercussions of prenatal genetic testing.Rapp combines the data she collected herself with historical context of amniocentesis and genetic counseling to argue that amniocentesis and those abortions following positive test results is a social decision as much as an individual one.
One method of performing a prenatal genetic test involves an amniocentesis, which removes a sample of fluid from the mother's amniotic sac 15 to 20 or more weeks into pregnancy. The fluid is then tested for chromosomal abnormalities such as Down syndrome (trisomy 21) and trisomy 18, which can result in neonatal or fetal death.

An invasive method involves probes or needles being inserted into the uterus, e.g. amniocentesis, which can be done from about 14 weeks gestation, and usually up to about 20 weeks, and chorionic villus sampling, which can be done earlier (between 9.5 and 12.5 weeks gestation) but which may be slightly more risky to the fetus.
