Many of you have probably heard about Harmony Test, but they don’t really know how it works and what it is for, so let’s have a look at it in details.
What is the Harmony prenatal test?
Harmony is a safe blood test that screens for specific chromosome conditions in a pregnancy as early as 10 weeks gestation.
When you’re pregnant, your blood contains tiny amounts of your baby’s DNA. The Harmony prenatal test looks at this DNA to provide accurate information about the likelihood for the most common chromosome conditions such as Down syndrome (trisomy 21), Edwards syndrome (trisomy 18), and Patau syndrome (trisomy 13).
What else can the Harmony test do?
In addition to screening for the conditions listed above, you and our experienced Sonographer and phlebotomist can talk about which of the following additional options might make sense for your pregnancy.
- Fetal sex – So you know whether your baby is male or female (also available with twins)
- Monosomy X – Also called Turner syndrome, a condition where a female is missing an X chromosome, and as a result, may have heart, endocrine, and learning problems.
- Sex Chromosome Aneuploidy – Differences in the number of X and Y chromosomes which can result in certain learning and/or behavioral challenges in addition to other health issues.
Should you have this screening?
The Royal College of Obstetricians and Gynaecologists welcome the news that non-invasive prenatal testing has been recommended for high-chance women on the NHS and states that it reduces unnecessary invasive procedures.
Down syndrome does not typically run in families and can happen in any pregnancy. Although the chance of having a baby with Down syndrome increases with age, most babies with Down syndrome are born to women under 35.
HARMONY VERSUS TRADITIONAL TESTS FOR DOWN SYNDROME
Does a low risk result mean that your baby does not have Down Syndrome?
No, any screening test carries a risk of a ‘false negative’. However, the risk of this happening with the Harmony is much lower than with conventional Down screening.
If you have a high risk result does that mean that mean that your baby’s chromosomes are abnormal?
No, not necessarily. It means that there is a higher risk and you will be offered the option of amniocentesis to assess the chromosomes directly. You will be offered support and counselling to help you reach that decision.
What if you have twins?
The Harmony Non-Invasive Prenatal Test and technology can also be applied to twin pregnancies, but is not suitable in the case of a vanishing twin.
Will you always get a result?
3 out of 100 women will require a repeat test. When the test is repeated, we receive a result in approximately two thirds of these samples. Patients will not be charged if we are unable to obtain a result.
What are the our prices and where are the samples sent to?
For the full test, which includes an ultrasound scan, the price is £460.
If you’ve already got a scan that is not older than 7 days, by bringing your ultrasound report, you can do the bloods only and the price of the test will be £380.
Samples will be sent by courier and processed at TDL Genetics in London, UK.
The all service is confidential and every effort has been made to ensure your personal information is held securely.
But what happens when you decide to have a Harmony prenatal test?
- At 10 weeks or later your blood is drawn.
- Your blood sample is sent to a laboratory in London, where it is analysed.
- Your results are sent to East Anglia Ultrasound Services in about 3-5 business days from receipt of sample in the laboratory.
Why you might want to chose Harmony?
For clear answers
Screening with the Harmony test identifies more than 99% of pregnancies with Down syndrome, whereas traditional screening misses as many as 20% (1 in 5).
For fewer false alarms
The Harmony test performance is superior to traditional screening for Down syndrome.
With the Harmony test, there is less chance your doctor will recommend follow-up testing due to a false-positive result, and you can avoid needless anxiety.
For information you can trust
All results will be given to you by your healthcare provider and will be interpreted in the context of your medical details and family history. You should continue with your usual scan appointments before and following the testing.
The Harmony prenatal test offers a highly accurate and proven screening test, giving confidence in the result.
What to expect from Harmony results:
The Harmony test is a screening test. That means it looks for evidence of the conditions listed above, but like any screening test, it does not provide a diagnosis.
Your Harmony test results can guide the discussions you have with your doctor about your pregnancy care.
A small proportion of NIPT tests may not produce a test result, for example if a suitable amount of the babies DNA was not present in the mother’s blood. In this case we will offer you a free redraw.
So… Don’t wait any longer, BOOK NOW your Harmony NIPT!
