Down’s Syndrome is the most common cause of learning disability. It is a chromosomal abnormality caused by the presence of an extra chromosome 21. The chance of having a baby with Down’s Syndrome increases as the mother gets older but there is a risk for women of all ages. The Combined Test is a screening test that measures various ultrasound and biochemical (substances in the mothers blood) markers to give an individualised risk of a pregnancy being affected with Down’s Syndrome.
The ultrasound markers that are utilised for the test are measurement of the nuchal translucency, presence or absence of the nasal bone and tricuspid regurgitation, assessment of flow in the ductus venosus and detailed examination of the babies anatomy. Maternal blood is also taken to measure levels of Beta Human Chorionic Gonadotrophin (the pregnancy hormone) and Pregnancy Associated Plasma Protein A (a protein produced by the developing placenta). The findings from the various assessments are then combined to give an individualised risk of the pregnancy being affected by Down’s Syndrome. The Combined Test can be performed between 11 weeks and 13 weeks and 6 days of pregnancy.
A risk of 1 in 300 or greater is considered to be “screen positive”. Women with a screen positive result will be offered counselling and a definitive diagnostic test i.e. CVS or amniocentesis.

I’ve been coming here for a few years now for my obstetric care and the doctors are nothing if not excellent and highly professional. I see Pat O’Brien (obstetrician) who is fantastic and Pran Pandya (scanning and fetal medicine) , who is brilliant. Also nice that they are always on time and never make you wait.
Dr. Sadia Bhatti highly exceded our expectations and we absolutely recommend her. She is a very experienced and talented professional who displayed the highest degree of technical skill and empathy.
Meeting Dr. Bhatti reassured us that we could have a positive birth despite the challenges. She explained the options and empowered us to make the choices that felt right for our circumstances. We opted for a gentle csection, and it was the most beautiful birth.
Thank you will never be enough! We will never be able to fully express how grateful we are to you for everything you did…
Thank you again for all of your help and excellent care during my pregnancy. I am very grateful.
Thank you for safely delivering our 3 children. You made every experience so pleasant! We always felt safe in your hands!
It’s not just skill that makes a good doctor but caring as well. Thank you for the concern and expertise you displayed throughout the pregnancy and birth. I truly felt that I was in good hands. We look forward to using you again some time in the future, please G-d!
Little things make a big difference. Appointments to fit your schedule and always on time, very friendly service and meeting the same people for your appointments is very reassuring.
