Down's syndrome Scan
Down's syndrome Scan - Nuchal Translucency Scan
11 Weeks + 6days - 13 Weeks + 6days
Brayford Studio Lincolnshire is the only recognized and accredited private centre in Lincolnshire by the Fetal Medicine Foundation, (FMF), and King's College in London, UK. Our sonographers are all accredited by the fetal Medicine Foundation also. Ultrasound scan screening is for Down's syndrome as well as Edward's syndrome and Patau's syndrome and Turner's syndrome. The ultrasound scan measures the nuchal translucency thickness and the presence or absence of the nasal bone of the baby as the majorities of babies with Down's syndrome may have an increase in the fluid collection behind the baby's neck and may also have absent fetal nasal bone. Nuchal translucency measurements as well as the blood test in the first trimester of pregnancy (The Combined Test) may avoid the needs for amniocentesis. The latter may have up to 1% risk of miscarriages of normal pregnancy due to the amniocentesis itself. Our cut-off point for nuchal translucency measurements are: 3mm, and that of the risk score is: 1 in 300. Nuchal translucency on its own picks up approximately 74% of cases of Down's syndrome. If combined with the nasal bone and the blood test the pick up rate of Down's syndrome may be increased up to 97% with 3% - 5% false negative and 3% - 5% false positive results. The result of the nuchal translucency scan is given to patients following counseling on the same day. The blood test results in 24 hours. We do not do the blood test at the Brayford Studio Lincolnshire but we can arrange it for you on request.
Nuchal Translucency Scan for Down's Syndrome, Edward's Syndrome, Patau's Syndrome and Turner's Syndrome
This 2D ultrasound scan is recommended to all pregnant women in the antenatal period. Nuchal translucency can only be performed between 11 weeks + 6 days & 13 weeks + 6 days, from the first day of your last menstrual period. If you are not sure of your dates, it may be necessary for you to have a dating scan prior to your nuchal scan.
Nuchal translucency is a screening test for Down's Syndrome, Edward's Syndrome, Patau's Syndrome and Turner's Syndrome. It will not tell you if your baby has, or has not got Down's Syndrome, Edward's Syndrome, Patau's Syndrome or Turner's Syndrome but it will tell you the risk of your baby being affected by Down's Syndrome, Edward's Syndrome, Patau's Syndrome or Turner's Syndrome and if you are at a high or low risk.
The nuchal translucency scan measures the thickness of the fluid beneath the skin behind the baby's neck. In Down's Syndrome, Edward's Syndrome, Patau's Syndrome and Turner's Syndrome there is an increase in the amount of this fluid. The scan alone picks up 74% of cases of Down's Syndrome, Edward's Syndrome, Patau's Syndrome and Turner's Syndrome, if it is combined with nasal bone screening, the blood test and the presence or absence of tricuspid valve incompetence the pick up rate increases to 95%.
Your Blood test at the Brayford studio Lincolnshire:
Multiple markers in maternal blood as well as ultrasound are used to calculate the risk for the common chromosomal abnormalities. This includes Down’s syndrome and Edward’s syndrome. The former is ten times commoner than the latter.
Neural Tube Defects (NTD’s), including spina bifida are also screened for using this Multi- Marker Screening Down’s syndrome risk of over 1 in 250 is regarded as a high risk. Patients of this risk and above should consider Chorionic Villous Sampling (CVS) in the first trimester or amniocentesis in the second trimester of their pregnancy.
Our blood test (The Admark blood test) that is performed in conjunction with the nuchal translucency scan is unique. It is far more superior than any other blood performed anywhere else. We measure four ingredients in the blood at the first trimester. The includes: Alpha-feto protein,AFP, Oestriol,uE3, free-beta Human chrionic gonadotrophin,hCG, and Placental protein A,PAPP-A. This in addition to the nuchal translucency scan measurements making them Five components which are being taking into consideration when calculating the risk of Down’s syndrome in the first trimester. Unless the result showing a low risk score, a further Four (AFP,UE3,free-beta hCG & inhibin-A) blood Markers are further analysed during he second trimester Free of charge to clarify any border line or high risk results that had been performed previously during the first trimester. This means that there are Nine variables in total that are used to quantify the risk with the resultant increase in the sensitivity and specificity of the screening test.
