What is NIPT (Non-Invasive Prenatal Screening)?

Non-Invasive Prenatal Screening is an advanced screening test for 3 chromosomal anomalies:

    • Down’s Syndrome (Trisomy 21 – >99% detection rate)
    • Edward’s Syndrome (Trisomy 18 – 97.4% detection rate)
    • Patau’s Syndrome (Trisomy 13 – 93.8% detection rate)

The test is highly accurate with false positive rates <0.1% for all 3 trisomies. Detection and false positive rates are calculated at a risk cut-off of 1/100. The Fetal Sex detection is >99% accurate.


Harmony Test‘ is a brand name for NIPT – we chose this test as it is the most established and reliable test available with analysis perfomed in London by TDL Genetics.

Please call us or visit our website for more information on the Harmony Test. 


Why do I need to have an ultrasound with the Harmony Test?
Ultrasound is a vital part of fetal screening. The laboratory requires a confirmation of viability and gestational age by the clinic submitting each Harmony Test. As such, we cannot offer a standalone NIPT blood test, even if you have recently had a scan elsewhere.

NIPT is a highly effective screening test for 3 chromosomal anomalies, however it is unable to screen for structural anomalies such as heart or brain defects which are more common and often more serious than Down’s Syndrome.


Here at City Ultrasound we specialise in early detection of fetal anomalies, the fetal heart and the fetal brain.



Our advanced expertise and ultrasound technology allow us to perform a comprehensive anatomical examination from as early as 10 week.
