In amniocentesis, a thin needle is inserted through the mother's abdomen into the sac around the baby under sonographic guidance. A small amount of fluid is withdrawn and sent to a laboratory. Cells are cultured, and the baby's chromosome make-up is reported in approximately two weeks. In addition, the amount of a substance called AFP is determined, which gives information about some structural defects, such as spina bifida. The procedure is brief and causes minimal discomfort. It is a relatively safe procedure, with little risk to the pregnancy. Amniocentesis is recommended for women over the age of 35 or for women who have a family history of inherited disorders. It can be performed any time after 14 weeks of pregnancy , but it is generally recommended between 15 and 20 weeks.
