What is the Harmony test?
The Harmony test analyses fetal DNA which can be found in a woman’s bloodstream when she is pregnant. Harmony assesses the risk of the fetus having any of the three most common Trisomy conditions: Downs Syndrome, Patau Syndrome and Edwards Syndrome (Trisomy 21, 18 and 13). Sex chromosome anomalies including Turner and Klinefelter syndrome can also be assessed (please note this is not available for twin pregnancies).
What does the screening involve?
The Harmony test will be performed in your own home by an experienced midwife, taking 30-45 minutes. Two vials of blood will be taken from your arm. These samples will then be sent tracked next day delivery to our laboratory who will analyse the blood for fetal DNA.
How accurate is Harmony screening?
With a >99% accuracy, the Harmony test is far more accurate than conventional screening currently offered on the NHS, which only detects 70-80% of fetuses with Downs syndrome. It is still a screening test and does not replace invasive diagnostics (with the risk of miscarriage), so if your result comes back as high risk you may still need to have invasive testing should you choose to.
Who is eligible to have the Harmony test?
Singleton and twin pregnancies from 10 weeks gestation are eligible for Harmony screening, including those conceived by IVF. Please note you need to have a scan prior to Harmony screening, either from the NHS or privately, in order to date the pregnancy and determine the number of fetuses in utero.
Where is my sample processed?
Results are processed in our London laboratory.
How long will it take to get a result?
Typically you can expect a result within 3-5 working days.
Can the Harmony test tell me the gender of my baby?
Yes, and this is included at no extra cost.
Our package includes:
- A telephone consultation to explain the procedure and explore your options (if required)
- A home visit to carry out the screening
- Confirmation of gender at no additional cost
- A follow-up telephone call to discuss the results if low risk, or a further home visit if high risk
- PLEASE NOTE: you will need to have had a scan (private or NHS) before we can undertake Harmony screening, to determine gestational age and whether you are having twins/multiples
