Nuchal Translucency Scan (11-14 weeks)

Fatima Gani - NTscan

Description- 11- 14 weeks scan- Mandatory
The NT Scan is an early non- invasive test for detecting markers that provide information on your risk for chromosomal abnormalities eg. Down’s syndrome. All mums carry a risk of chromosomal abnormality regardless of age. Theoretically older mums categorized over the age of 37yrs fall into a higher risk. 

11- 14 weeks, foetal measurement 45-80mm (Do not miss this time frame)

Interesting facts
* The embryo measures about 50-85mm including the legs
* The foetus will resemble a tiny human though the large head and bony features will mimic an “alien”

*It is the size of an avacado

Bring along a blood request form if you have one from your doctor. Notify us of any family history or previous pregnancies that exhibited any abnormalities. 

The sonographer will perform a trans-abdominal scan. The foetus will be measured from crown to rump and special skills are needed to measure the nuchal translucency (neck fold) and nose bone. Some co-operation is needed from the foetus to optimize position so this may take a few minutes. Results are immediate and a written report will be given to you to take to your doctor, midwife or clinic. A blood form will be issued to you which is taken to any Lancet Laboratory and they will draw blood from you. The result of the blood gives you a combined risk of your age, scan result and blood result. Blood results are ready within 7-10 days. 

We calculate your expected due date by comparing the first day of your last menstrual period with specific measurements of the foetus by measuring the distance from the top of the head (crown) to the bottom of the body (rump).These two usually correlate with each other.
