What is an Amniocentesis?

An amniocentesis is a medical procedure used during pregnancy to test for genetic conditions, chromosomal abnormalities, and certain infections. It involves inserting a thin needle into the amniotic sac (through the mother's abdomen) to withdraw a small sample of amniotic fluid, which surrounds the baby in the uterus. This fluid contains fetal cells and other substances that can provide important information about the baby’s health.

Why is Amniocentesis Done?

Doctors may recommend an amniocentesis for:

Genetic Testing – Detecting conditions like Down syndrome, Edwards syndrome, and neural tube defects.

Fetal Lung Maturity – Checking if the baby's lungs are developed enough for early delivery.

Infection Detection – Identifying infections that could affect the baby.

Paternity Testing – In rare cases, confirming biological relationships.

When is it Done?

Usually between 15 to 20 weeks of pregnancy.

Results take a few days to a few weeks, depending on the tests being done.

Risks & Considerations

Though generally safe, there are some risks, including:

A small chance of miscarriage (less than 1%).

Cramping or leaking amniotic fluid.

Infection (very rare).

It’s usually recommended for women at higher risk of genetic conditions, such as those over 35 or with abnormal ultrasound or blood test results
