  2. Amniocentesis - Wikipedia

    en.wikipedia.org/wiki/Amniocentesis

    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 ...

    en.wikipedia.org/wiki/Genetic_testing

    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.

    Amniocentesis is a test to check a baby's chromosomes. A small amount of amniotic fluid, which contains some fetal cells, is removed and tested. Amniocentesis is very accurate; however, there is a risk of miscarriage which occur in 0.5–1% of women who have amniocentesis. [2] Results take about two 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]

  6. Prenatal testing - Wikipedia

    en.wikipedia.org/wiki/Prenatal_testing

    There are three purposes of prenatal diagnosis: (1) to enable timely medical or surgical treatment of a condition before or after birth, (2) to give the parents the chance to abort a fetus with the diagnosed condition, and (3) to give parents the chance to prepare psychologically, socially, financially, and medically for a baby with a health problem or disability, or for the likelihood of a ...

    Chorion villus sampling (CVS) can be done at 11–14 weeks, and has a 1% risk of miscarriage. Amniocentesis can be done after 15 weeks, and has a 0.5% risk of miscarriage. Non invasive prenatal testing can be done around 10–12 weeks. [34] Another option in the case of unclear genetic test results is fetal muscle biopsy. [citation needed]

    It provides the earliest post-implantation test. A meta-analysis published in 2011 found that such tests are reliable more than 98% of the time, as long as they are taken after the seventh week of pregnancy. [1] [2] Chorionic villus sampling (CVS) and amniocentesis are two rather invasive testing procedures. These may, in principle, be ...
