Introduction
Amniocentesis is a prenatal diagnostic test carried out mainly between 14th to 18th week of pregnancy. Amniotic fluid is taken from the uterus, sent to a diagnostic laboratory and embryonic cells isolated from the amniotic fluid. No anaesthetic is required, and a result is usually obtained in about three to four weeks. When the test is carried out by an obstetrician experienced in the technique, the risk of a miscarriage related to the test is about 1 %.

Testing Comparison
A Chochrane review (2003) comparing prenatal diagnosis showed that early amniocentesis is not a safe as mid-trimester amniocentesis or chorionic villus sampling, because of increased pregnancy loss and the increased risk of Talipes equinovarus.
