Amniocentesis
A definitive diagnostic test for genetic conditions
Amniocentesis is a prenatal test used to detect certain genetic and chromosomal conditions in a developing baby.
In this procedure, a small amount of amniotic fluid—surrounding the baby inside the uterus—is carefully extracted using a thin needle under ultrasound guidance.
This fluid contains fetal cells, which are then analyzed in a laboratory.
The test is usually performed between 15 to 20 weeks of pregnancy and is considered highly accurate (around 99%) in identifying conditions such as:
* Down syndrome
* Cystic fibrosis
* Neural tube defects
Duration
20–30 minutes (procedure) + observation time
