  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 ...

    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.

    Fetal viability typically occurs at about 24 to 25 weeks of gestation. [2] When the fetus is in between the ages of 24–34 weeks, a glucocorticoid is given to the patient about 24 hours before the procedure to stimulate lung maturity. An ultrasound is performed before the procedure to view the position of the fetus and may be used during the ...

    However, this test has been taken off the market. Amniocentesis is another recommended method for testing antigen status and risk for HDN. Fetal antigen status can be tested as early as 15 weeks by PCR of fetal cells. [12] CVS is possible as well to test fetal antigen status but is not recommended.

    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 performed as early as the 8th and the 9th week of pregnancy.

    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.

  9. Genetic testing - Wikipedia

    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.
