Chromosome Aneuploidy | Amniocentesis

What is an amniocentesis? Amniocentesis is a procedure used to take out a small sample of the amniotic fluid for testing. This is the fluid that surrounds the fetus in a pregnant woman. Amniotic fluid is a clear, pale yellow fluid that: Protects the fetus from injury Protects against infection Allows the baby to move and develop properly Helps control the temperature of the fetus Along with various enzymes, proteins, hormones, and other substances, the amniotic fluid contains cells shed by the fetus. These cells have genetic information that can be used to diagnose genetic disorders and open neural tube defects (ONTDs), such as spina bifida. Testing may also be done to check for inherited gene defects and metabolic disorders based on the family history. Amniotic fluid also contains other substances that give information about the fetus. This procedure may be done in late pregnancy to check fetal well-being and diagnose fetal health problems, such as infection. If a baby is expected to be delivered early, amniocentesis may be done to check for fetal lung maturity. The fluid is sent to a lab so that the cells can grow and be analyzed. Results are most often ready in about 10 days to 14 days, depending on the lab. Results from fetal lung maturity tests are ready within a few hours. Problem: Diagnosis of chromosome aneuploidy of unborn children is normally done by a combination of amniocentesis, cell culture, and _______________.
