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 ...
Amniocentesis: This can be done once enough amniotic fluid has developed to sample. Cells from the fetus will be floating in this fluid, and can be separated and tested. Miscarriage risk of amniocentesis is commonly quoted as 0.06% (1:1600). [68] By amniocentesis it is also possible to cryopreserve amniotic stem cells. [69] [70] [71] After 15 weeks
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]

Many of these conditions are also impossible to diagnose until an amniocentesis or the anatomy scan of the fetus, which cannot be completed prior to 15 weeks and 18 weeks of gestation, respectively.
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.
A co-test of the two options could be another option, according to Davis. She said that while HPV testing may be preferred, the other options “are effective” and can “still be a choice for ...
