Our Sonographer needs to concentrate while scanning and may be able to answer some of your questions at the end of the scan. The scan will be reviewed by a MFM specialist and the report will be sent to your referring doctor for your next appointment. Any urgent matters will be discussed with you on the day.

Amniocentesis and Chorionic Villus Sampling (CVS)

Amniocentesis and CVS are prenatal diagnostic procedures to test your baby’s genetic information. Counselling will be done You will be counselled by your referring doctor to decide if this is an appropriate test for you. CVS is attended between 11-13 weeks of pregnancy and the amniocentesis will occur after you are more than 15 weeks pregnant. Amniocentesis procedure involves a very fine needle being placed into the amniotic fluid around baby and 18-20mls of fluid withdrawn. This is sent to The Children’s Hospital for genetic (chromosomal) testing. The procedure usually takes a few minutes only. Your body makes amniotic fluid all the time, the loss of 18-20mls does not affect the baby. CVS uses a fine needle to take a very small sample of the placental tissue to test the baby’s chromosomes. At WIMFM we only do abdominal CVS not transvaginal. The procedure takes about 10 minutes.
When you arrive you will be meet spoken to by the MFM Midwife who will explain the procedure and answer any of your questions. You will be asked to sign a consent form. This should take about 15-30 minutes.
If you are a negative blood group we will offer you an Anti–D injection after we have discussed this and you have signed a consent for Anti–D.An ultrasound scan will be attended to measure your baby. The doctor will then meet with you to answer any further questions before the CVS or Amniocentesis. Please read the After your Chorionic Villus Sampling or Amniocentesis fact sheet. This fact sheet will explain what to expect after these procedures and any emergency care options.


For Medicare card holders there will be no cost to you for any ultrasound scans. Non-Medicare patients are required to pay the standard consultation fee of $126, which is to be paid at the cashiers, so please allow 30 minutes before your scan to complete this payment.
For Medicare and Non Medicare patients who are having an Amniocentesis or Chronic villus sampling you may be offered the QFPCR (quick result) this carries a cost of $175, and you will receive a bill from The Children’s Hospital after the test is performed.
