What procedure is conducted to collect amniotic fluid for genetic testing?

• A. Chorionic villus sampling
• B. Amniocentesis
• C. Ultrasound
• D. Fetal monitoring

Answer: (B)

Amniocentesis is the procedure specifically designed for the collection of amniotic fluid, which is crucial for genetic testing. During this procedure, a thin needle is carefully inserted through the abdominal wall into the uterus, guided by ultrasound imaging, to withdraw a small sample of the fluid surrounding the fetus. This fluid contains fetal cells that can be analyzed for chromosomal abnormalities, certain genetic conditions, and other important factors related to fetal health.

In the context of genetic testing, amniocentesis is conducted typically between the 15th and 20th weeks of pregnancy, providing valuable information for potential genetic disorders such as Down syndrome or cystic fibrosis. The ability to collect and analyze this fluid makes amniocentesis a vital tool in prenatal diagnostics.

Other procedures mentioned, such as chorionic villus sampling, ultrasound, and fetal monitoring, serve different purposes within prenatal care. Chorionic villus sampling is another method for obtaining genetic information, but it involves sampling tissue from the placenta rather than amniotic fluid. Ultrasound is primarily used for imaging and monitoring fetal development, while fetal monitoring is focused on assessing the well-being of the fetus during pregnancy and labor. These distinctions highlight the specific role of amniocentesis in
