Amniocentesis
Abbreviation: Amnio
Amniocentesis is a diagnostic test usually performed between 15 and 20 weeks of pregnancy. Using continuous ultrasound guidance, a thin needle is passed through the abdomen into the uterus to withdraw a small sample of amniotic fluid, which contains cells shed by the baby. These cells are cultured and analysed to detect chromosomal conditions such as Down syndrome, as well as neural tube defects and some inherited genetic disorders. Results can take one to two weeks, though rapid testing for common trisomies may be available sooner. The procedure carries a small miscarriage risk of around 0.1 to 0.5% when performed by an experienced specialist.

Amniocentesis is available at restructured hospitals in Singapore including KKH and NUH, and is typically recommended after a high-risk screening result or following CVS that is inconclusive. Discuss your personal risk profile and anxiety around waiting time with your obstetrician before proceeding.
