This fluid contains cells from the baby that can be tested to analyze the baby's chromosomes. The procedure is usually performed under ultrasound scan using a fine needle. The risk of causing miscarriage by this procedure is between 0.5 - 1%. The results often take two to three weeks.

Anencephaly is a neural tube defect: a disorder involving incomplete development of the brain, spinal cord, and/or their protective coverings. The neural tube is a narrow sheath that folds and closes between the 3rd and 4th weeks of pregnancy to form the brain and spinal cord of the embryo. Anencephaly occurs when the "cephalic" or head end of the neural tube fails to close, resulting in the absence of a major portion of the brain, skull, and scalp. Infants with this disorder are born without both a forebrain (the front part of the brain) and a cerebrum (the thinking and coordinating area of the brain). The remaining brain tissue is often exposed -- not covered by bone or skin.
