Unlike standard blood tests or ultrasounds, amniocentesis is an invasive test that provides definitive results about fetal genetics. It examines actual fetal cells from the amniotic fluid, not just risk estimates. This makes it unique for parents who need clear answers about serious conditions.

Key Differences

• Ultrasound: Shows physical development, estimates risk.
• Blood tests: Screening, indicates probability of conditions.
• Amniocentesis: Confirms diagnosis with fetal cells - high accuracy.
• Considerations: Slight amnio risk due to the invasive nature.
