Invasive Prenatal Diagnostic Procedures
Tests such as amniocentesis or chorionic villus sampling obtain a sample to investigate specific fetal genetic or chromosome concerns.
Different procedures
Amniocentesis samples amniotic fluid, while chorionic villus sampling takes a small sample from the placenta. These are prenatal diagnostic tests, not general keyhole operations.
Before deciding
A specialist explains why a test is being offered, when it can be performed, what the laboratory will examine and its limitations. Both procedures carry risks, including a small risk of pregnancy loss.
Aftercare
Follow the procedure-specific instructions and contact the treating team for significant pain, bleeding, fluid leakage or fever. Ask how results and any necessary follow-up will be arranged.
This information supports a discussion with your doctor. Suitability, availability and any specialist referral should be confirmed with the hospital. Individual care plans and outcomes vary.
