It has been discovered that a blood sample taken from the mother can be analysed for cell free fetal DNA, which is essentially a marker in the mother’s blood of the DNA of the baby. The result of the simple blood test (Harmony NIPT), taken from 10 weeks onwards has a high sensitivity for the detection of Downs syndrome, Edwards syndrome and Patau’s syndrome, which may reduce the need for invasive testing by CVS or amniocentesis. This is great news for expectant couples. It is important that an ultrasound scan is performed just before the blood test to confirm the pregnancy, and to check if the mother is carrying twins or more. The Harmony test can also be performed for twin pregnancies and can now be used if the pregnancy is conceived with donated egg.
Anyone who wants extra reassurance during their pregnancy can have the test. Women who may need it are those who are anxious about their baby having a chromosomal condition such as Downs, Edwards or Patau's syndrome, Older women (particularly over 40 years) and those who have already had a chromosomal condiition in a previous pregnancy often opt for the test. Those who are at particular risk of miscarriage should they have an amniocentesis or chorionic villous sample also find the test very attractive as it avoids an invasive procedure. It is helpful for those who have had a previous sex chromosome condition such as Turners syndrome.
The result is available within 3-10 working days, the normal turnaround time is 5 working days. There is a 3% chance that there will be no result obtained. There are a variety of reasons for this. This is not a positive or negative test: it is an unsuccessful test. An offer of a repeat test is made free of charge. This is usually successful. In rare circumstances the result can take longer than 7 days. We understand it can be a stressful time waiting for results and we will endeavour to communicate any delays to our patients as soon as we receive information from the laboratory.
The result is expressed as a probability. It is a screening test and not a diagnostic test. A result form of a low probability test is shown below. A low probability test result gives a probability of a chromosomal problem of less than 1:10000. A high probability result gives a probability of greater than 99%. A high probability result does not confirm that the baby has the chromosome abnormality. An amniocentesis or chorionic villous sampling is necessary to give a diagnosis. The couple are counselled about this.
The test is currently £500 including the ultrasound scan when done on a weekday. Appointments after 5.00pm will carry a £50 surcharge. If you would like to come in on a Saturday or Sunday the cost is £550.
Depending on how many weeks pregnant you are, you will still have the opportunity to have a 12 week scan privately or with the NHS. The focus of the 12 week scan will change as you will already have the result of the Downs syndrome test, so the 12 week scan will look at the baby in detail for structural conditions (these may exist without a chromosomal condition). You will still have the opportunity to have the later scans, such as the 20 weeks scan, as before. If the Harmony test is low probability then it is important that the person conducting the 12 week scan is aware of this. If the test is high probability then you should return to The Birth Company or a good NHS unit for further counselling.
Yes. Structural abnormalities such as Spina Bifida, heart defects and a poorly growing baby will only be seen on scans and often not until later scans. These scans should still be undertaken.

We had received possible worrying news from our NHS anomaly scan, without much information provided or confirmation. I am so pleased that we came to The Birth Company for reassurance, as we are now extremely happy that everything is fine. Shahrzad was fantastic and went through the whole anomaly scan thoroughly, explaining everything and looking in detail at each area. Nothing was rushed and she took her time to make sure baby was in the correct position to get the best results. We can’t thank her and Dr Gibb enough for the confidence they have given us. Would highly recommend The Birth Company for all scans.
' Professional and reassuring 'Helen Campbell
The sonographer was ready as soon as I arrived, and she was extremely calming, personable and professional. The scan and blood test where efficient without feeling rushed and all very easy. These appointments can feel uneasy and make you feel anxious but I felt reassured and in professional hands the whole time
I saw Kate throughout my first pregnancy and am now doing so again with my second. She is absolutely amazing, she explains everything really clearly, and has answered all sorts of bizarre questions and worries I have had. On top of being clinically excellent she is also just the loveliest person and always a pleasure to see.Sarah Elliott
We had the harmony test with the Birth Company and had a reassurance scan with sonographer Kirsty McGarry who was absolutely lovely and really put our minds at rest. We had been scared by our NHS dating scan and left feeling like there was something wrong. We explained the situation and was treated very professionally and with good care. Also speedy appointments also as I had phone in the morning and got an appointment by afternoon. So thankful.Ashley and Tom
Really friendly, efficient service. Great experience overall. Had the Panorama. My appointment was with Kate who was absolutely fantastic. The results came really quickly. Have a comparison with private healthcare elsewhere and must say that The Birth Company was just how I would like to be treated when I pay for medical services - attentively, calmly, friendly, in a pleasant environment that doesn't look like hospital. Top marks!Anna

The Birth Company has been excellent, providing timely scans and blood tests during my IVF treatment abroad. Staff are always friendly and extremely efficient. I would highly recommend coming here.
' Professional and friendly 'Lyndsey Dilla
When I first contacted the Birth Company I spoke to Danielle. She was fantastic. She went above & beyond to put me at easy & make the journey from Kent as stress free as possible. Every staff member that myself and my husband have come into contact with have been approachable, professional and friendly. Kate scanned me the first time and put me completely at easy. Lisa on reception is professional and very approachable. Highly recommended
' Highly recommended 'Emelie
Donald was so lovely! I was so nervous as I have a bad history and he was super quick and confirmed my baby's heartbeat as quickly as he could. He spent time showing me the baby and the anatomy and it was the best money I have ever spent! The reception girls were lovely too - considering they deal with babies day in day out they were super excited for me! Thank you so much one and all! If only I lived in London and could have all my scans with you!
