Amniocentesis is a medical procedure for detecting genetic disorders and birth defects in a fetus. It involves extracting a small quantity of amniotic fluid from the sac surrounding the fetus. This fluid contains fetal cells that are subsequently analyzed for genetic abnormalities.
Other methods are not primarily employed for detecting fetal defects in the same manner:
- While ultrasound can identify structural anomalies, it does not provide definitive genetic analysis.
- Blood tests can assess for specific conditions but do not directly analyze fetal genetic defects.
- Genetic screening examines the genes of parents or the fetus, but amniocentesis offers more specific direct fetal testing.
