Before having amniocentesis, your doctor will explain the benefits, risks and any alternative tests that may be appropriate.
If you decide to have the amniocentesis test, you will probably be asked to sign a consent form.
The amniocentesis procedureBefore amniocentesis is carried out you will usually have an ultrasound scan. This will enable the doctor to decide where to remove the amniotic fluid from.
Some people opt for having part of their abdomen numbed with anaesthetic before the needle is inserted. This is just a small injection in your tummy. A longer, thin needle is used to extract the fluid. The needle is inserted through the wall of your abdomen and into the sac of fluid surrounding the foetus. A small sample of amniotic fluid is taken using a syringe. This fluid will be sent to a laboratory for analysis. The test doesn't usually take more than half an hour and you may feel a bit uncomfortable during the procedure. It is recommended that you rest for 24 hours after having amniocentesis.
