Amniocentesis is an invasive test you get during pregnancy to check for certain genetic disorders or defects, or other health problems your baby may have. Unlike non-invasive prenatal tests, it not only looks for the possibility of trisomies, but also health issues.
This test involves extracting a sample of amniotic fluid from the sac, using a needle inserted through the mother’s womb. In many places they choose to use local anesthesia, and it is a test that incurs many risks, including miscarriage.
The test is carried out between weeks 15-20 of pregnancy, it is recommended by a health professional, and it must be carried out in authorized and certified clinics for it. It is also used to be able to carry out a paternity test during pregnancy, but this is not its main purpose.
