Down’s Syndrome & 12 week Nuchal Scan

This is my offers peace of mind for Down’s Syndrome Screening.

Sometimes the screening process is worrisome. Many women receive unnecessary high-risk results and the waiting is worst of all. We aim to strip away all the confusion about screening and provide you with the safest, most accurate and advanced screening services available so that you can relax, feeling fully informed and confident that you made the right choice.

All of our screening tests incorporate an ultrasound scan of your baby to check well-being. We also look at a number of ultrasound markers for both the risk of a chromosomal abnormality and those associated with structural problem including cardiac and spina bifida.

Non-invasive prenatal testing (NIPT)

10-20+ weeks

(Ultrasound Scan and cell free fetal DNA analysis)

1 in 30 women will be given a high risk result with the NHS combined screen but most of these babies will be normal. If you fall into this high risk group you will be offered an amniocentesis or CVS. The possibility of miscarriage now becomes a real threat. There is an alternative and it’s the best reassurance any parent would want so they can protect their unborn baby.

This new non-invasive prenatal test will detect over 99.5% of babies affected with Down’s syndrome and other chromosomal abnormality and less than 1 in 3000 women will be given a false positive screen result.

Addmark® screening

11-13 weeks

(Combined Screen using Ultrasound Scan and Maternal Blood Sample)

Addmark® measures the nuchal translucency in addition to other anatomical markers and combines these factors with up to 8 placental maternal blood biochemical markers, taken from a simple blood sample to assess your chromosomal risk.

Addmark® is superior to the NHS Combined Screening test for detecting Down’s Syndrome and can also detect the risk of other trisomy conditions such as Edward’s and Patau Syndrome plus structural defects as a first trimester anatomy check is also performed.

This screening also has a greatly reduced chance of a false-positive high-risk result from 1 in 30 with the combined NHS screen to less than 1 in 166 with Addmark®. Let Addmark® give you greater peace of mind and reduce the need for invasive procedures that carry risk of miscarriage.

Nuchal+ screening

11-13 weeks

(Ultrasound Scan only)

The nuchal scan is the basis for screening for Down’s Syndrome and other abnormalities and measures the fluid under the skin at the back of baby’s neck as a means to identifying high-risk pregnancies.

In order to get the optimal risk assessment, Nuchal screening used in isolation to screen for chromosomal risk, is best performed in the hands of experts who specialise in screening for chromosomal abnormalities .

The NHS combined first trimester screen using nuchal scan and 2 maternal placental biochemical markers aims to detect up to 90% of pregnancies affected with Down’s syndrome but a worrying 1 in 30 women will receive a positive high-risk.

At this is my, because we check and measure more anatomical markers in addition to the Nuchal Translucency (NT) measurement, we are able to more effectively calculate risk and lower your chance of receiving a false positive result.

Currently to-date we have never failed to obtain a nuchal measurement and calculate risk assessment. Our expertise is your reassurance. Call immediately if your NHS screen has failed.

Genmark screening

14-20 weeks

(Combined Screen using Ultrasound Scan and Maternal Blood Sample)

Don’t worry if you have missed your first trimester screening, this is my offers a combined test for patients who have missed this window of opportunity. Genmark is the option for you in the second trimester and can be performed up to 20 weeks. Again, it combines ultrasound and blood markers to calculate a risk, and again, it is better than the second trimester triple or quadruple blood test available via the NHS.

With all our chromosomal screening tests the growth, well-being and anatomy of the baby is checked to give patients reassurance at this early stage that all is well.
