Antenatal Screening & Harmony Test

Harmony screening test


A non-invasive prenatal test (NIPT) that looks at the chromosomal abnormalities in the baby's DNA. This can be 99% accurate (the conventional screening currently offered on the NHS only detects with 70-80% accuracy) in detecting abnormalities for the three most common Trisomy conditions: Down's Syndrome, Patau's Syndrome and Edward's Syndrome (Trisomy 21, 18 and 13). Sex chromosome anomalies including Turner and Klinefelter syndrome can also be checked. The baby's gender can also be tested for and is included in the fee.


The Harmony test is still a screening test and does not replace invasive diagnostics (with the risk of miscarriage). If your results come back as high risk, you may still choose to have invasive testing which will give you a 100% diagnosis.


Please note you will need to have had an ultrasound scan to check your baby's gestation and whether you are having twins/triplets.


What is involved:


our midwife will come to your home to obtain two samples of blood and answer further questions.

These samples will be sent to the laboratory in London for analysis (results back in 3-5 working days).

A phone call and email to follow if your results show low risk. A home visit will be required if the results come back as high risk.


Please contact us to discuss your individual needs and how we can help you.
