Sampling of the fluid in the amniotic sac. In humans this is carried out, between the 12th and 16th week of pregnancy, by inserting a needle through the abdominal wall into the uterus. By karyotyping the cells and determining the proteins present, it is possible to determine the sex of the foetus and whether it is suffering from certain congenital diseases such as Down's syndrome or spina bifida.
Amniocentesis (also referred to as amniotic fluid test or AFT) is a medical procedure used in prenatal diagnosis of chromosomal abnormalities and fetal infections, and also used for sex determination in which a small amount of amniotic fluid, which contains fetal tissues, is sampled from the amniotic sac surrounding a developing fetus, and the fet...Found on http://en.wikipedia.org/wiki/Amniocentesis

A prenatal diagnosis method in which a needle is inserted into the amniotic sac that surrounds the baby under the guidance of ultrasound. Some of the amniotic fluid is drawn up through the needle. Within the amniotic fluid are cells from the baby. These cells contain the baby's DNA which is used for genetic testing, including testing for single gen...Found on http://www.childrenshospital.org/centers-and-services/division-of-genetics/

Amniocentesis-Sometimes called an `amnio`, this minor surgical diagnostic test allows the doctor to obtain a sample of the amniotic fluid by inserting a long, thin, hollow needle through the mother's abdomen into the uterus. The amniotic fluid is then analysed to look for genetic characteristics of the baby.
