It involves removing and testing a small sample of cells from amniotic fluid, the fluid that surrounds the unborn baby in the womb uterus. Amniocentesis is not offered to all pregnant women. It's only offered if there's a higher chance your baby could have a genetic condition. It's important to remember that you do not have to have amniocentesis if it's offered.
It's up to you to decide whether you want it. A midwife or doctor will speak to you about what the test involves and let you know what the possible benefits and risks are to help you make a decision. Find out about why amniocentesis is offered and deciding whether to have it. Amniocentesis is usually carried out between the 15th and 20th weeks of pregnancy, but you can have it later if necessary.
It can be performed earlier, but this may increase the risk of complications of amniocentesis and is usually avoided. During the test, a long, thin needle is inserted through your abdominal wall, guided by an ultrasound image. The needle is passed into the amniotic sac that surrounds the foetus and a small sample of amniotic fluid is removed for analysis. Most women report only mild discomfort during the procedure. Guided by ultrasound, your health care provider will insert a thin, hollow needle through your abdominal wall and into the uterus.
A small amount of amniotic fluid will be withdrawn into a syringe, and the needle will be removed. The specific amount of amniotic fluid withdrawn depends on the number of weeks the pregnancy has progressed. You'll need to lie still while the needle is inserted and the amniotic fluid is withdrawn. You might notice a stinging sensation when the needle enters your skin, and you might feel cramping when the needle enters your uterus.
After amniocentesis, your health care provider will continue using the ultrasound to monitor your baby's heart rate. You might experience cramping or mild pelvic discomfort after an amniocentesis. You can resume your normal activity level after the procedure. However, you might consider avoiding strenuous exercise and sexual activity for a day or two. Meanwhile, the sample of amniotic fluid will be analyzed in a lab.
Some results might be available within a few days. Other results might take up to four weeks. Your health care provider or a genetic counselor will help you understand your amniocentesis results.
For genetic amniocentesis, test results can reliably rule out or diagnose various genetic conditions, such as Down syndrome. However, amniocentesis can't identify all genetic conditions and birth defects. If amniocentesis indicates that your baby has a chromosomal or genetic condition that can't be treated, you might face wrenching decisions — such as whether to continue the pregnancy.

A procedure for finding certain disorders in a fetus during pregnancy. In amniocentesis, a small amount of the salty liquid that surrounds the fetus in the amniotic sac is drawn out through a needle inserted into the mother's abdomen.
The fluid generally contains some isolated cells from the fetus.
