In this test a small amount of the fluid (10-15mls) that surrounds your baby is taken by using a fine needle that is inserted into the womb. The needle is guided by ultrasound at all times so that it doesn’t harm your baby.

The results from this test take 48-72 hours to exclude Down’s syndrome and two very uncommon chromosomal anomalies (Trisomy 18 and 13). The cells are then further cultured for 10-14 days. Up to half abnormal results show chromosomal problems other than Down’s syndrome.

The results will be fully discussed with you by a specialist in fetal medicine and how any abnormal results will affect the baby.

The cost of the consultation, scan and amniocentesis is £485.00 and you receive a medical written report. We will also ask if you would like a copy of the report sent to your GP
