When does a doctor order an amniocentesis?

Answer by  howliecat (73)

Women over the age of thirty-five have a greater chance of carrying a child with chromosomal abnormalities and it is increased if there is a family history of genetic problems. In this event a doctor may order an amniocentesis, a procedure that tests fluid from the amniotic sac to determine if the baby is at risk.

Sometimes a doctor will do one if the mother is over 40. Other times they will do it if they think there is a problem or family history of defects.

If something in your blood-work early in the pregnancy indicates an elevated risk of a birth defect like Down's syndrome, the doctor may recommend an amniocentesis to verify it.

Your doctor might order an amniocentesis based a family history of a genetic abnormality, if an ultrasound showed the possibility of a birth defect, or if the mother is over a certain age.

An amniocentesis is usually ordered to detect genetic abnormalities. It is often suggested to women over 35 to detect chromosomal abnormalities. The test involves taking a sample of the amniotic fluid. Doctors will also look at family history and any possible birth defects. The test can help decide on the best plan of action for the fetus and delivery.
