When to take an amniocentesis test?

An amniocentesis test is a procedure where a small sample of amniotic fluid from your uterus is taken to detect birth defects. The amniotic fluid that surrounds and protects the fetus inside your uterus. Cells from the fetus that float in the fluid can be examined for chromosomal defects, like Down syndrome. The fluid can also be tested for neural tube defects, such as spina bifida.


There are three conditions under which you need to take an amniocentosis test: 

* you’re 35 years old or older

* you have a family history that increases the risk of certain birth defects or other disorders

* you’ve had a child with a major birth defect
