HARMONY TEST USED TO BE THE GOLD STANDARD IN NIPT
Introduced in 2013, it gained popularity quickly among UK healthcare providers. In recent years, Harmony has lagged behind other NIPT technologies. This has resulted in TDL – the lab providing the test, discontinuing the test across the UK. END OF AN ERA…
TDL Genetics ends Harmony NIPT provision after a decade. With outdated technology, high no-call rates, and fierce competition, Harmony loses its shine. As leading NIPT providers, we’re reviewing TDL’s new offering.
TDL ( Previous Harmony ) NIPT Illumina VeriSeq v2
The Illumina VeriSeq v2 prenatal test is a new non-invasive prenatal screening test (NIPT) which can be performed from 10 weeks of gestation.

Illumina VeriSeq v2 is much more accurate than first-trimester blood screening and ultrasound tests

TDL (Previous Harmony ) VeriSeq v2 NIPT Prenatal NIPT - An Overview
According to the International Society for Prenatal Diagnosis (ISPD) and the American College of Medical Genetics and Genomics (ACMG), Non-Invasive Prenatal Testing (NIPT) is a primary prenatal screening blood test for pregnant women of all ages. It is a method that determines whether the fetus will be born with genetic abnormalities. The NIPT Blood test serves as a first-line screen for the diagnosis of chromosome abnormalities. Infants born to mothers above 35 years of age are more likely to have Down Syndrome and other chromosomal conditions. NIPT also detects microdeletion syndromes that occur in infants regardless of their mother's age.
TDL (Previous Harmony ) VeriSeq v2 NIPT is the cell-free DNA-based non-invasive prenatal test that screens for specific genetic conditions in a pregnancy as early as 10 weeks of gestation. Miracle Inside Diagnostic Centre near Harrogate provides TDL (Previous Harmony ) VeriSeq v2 NIPT Genetic Testing, which is a proven NIPT blood test that delivers high-quality and reliable results. It has a 99% detection rate for Down Syndrome and will also identify most cases of Edward Syndrome and Patau Syndrome.
Who is it suitable for?
The TDL (Previous Harmony ) VeriSeq v2 NIPT Test is suitable for any pregnant woman with a singleton or twin pregnancy (except donor twin pregnancy).
Typically, the test is useful for the following patients:
Women over 35 who are concerned about their age-related risk of Down Syndrome and other Trisomies.
Women under 35 who want a safe, reliable, early, and accurate test for Down Syndrome
Women who have an increased risk or “High Risk” result from a Combined Test or Nuchal Translucency scan but wish to avoid unnecessary CVS or amniocentesis, and their risk of miscarriage.
Women who have an increased risk or “High Risk” result from a Triple test or Quad test but wish to avoid unnecessary CVS or amniocentesis and the risk of miscarriage.

Why do we think the Illumina VeriSeq is superior to the Harmony?
- Better detection rates for all 3 trisomies (> 99%) – Harmony is 99% for trisomy 21, 97% for trisomy 18, & 93% for trisomy 13.
- Only 1% of samples will fail in processing – Harmony has a 4% failure rate.
- Shorter turnaround times (Usually 3 – 4 working days) – Harmony is 5 – 7 working Days.
- PPV (positive predictive value) same as the Harmony Test.
- American-originated test analysed by the largest NIPT Lab in the UK (TDL Genetics) – one of the only Labs with UKAS accreditation for NIPT testing (same as Harmony test) – other laboratories often do not have UKAS accreditation for NIPT testing.
Gender Confirmation
The earliest you can have a scan to know Baby’s Gender is around 16 weeks, and the NHS don’t tend to provide gender confirmation until 20 weeks. A NIPT test can be performed from as early as 10 weeks, with the results arriving in 7 working days.
What do about my Regular NHS 12-week scan and NT measurement scans?
If you are having an NIPT Test or you have got a negative or Low-risk result on the Non-Invasive Prenatal Test, even then you should not miss your regular 12-week NHS scan and the NT measurements.
What if the sample fails?
Statistically, the failure rate is 3 % to 4%. If there is not enough cell-free DNA in the blood sample to analyse, we will again take a new sample at no extra cost.
What if I have a high BMI?
There is a high chance of getting inconclusive results as women with high BMI have a reduction in the proportion of cell-free fetal DNA.

Frequently Asked Questions (FAQs)
What is the Harmony NIPT test?
The Harmony NIPT (Non-Invasive Prenatal Test) is a safe blood test taken from the mother that analyses cell-free fetal DNA in the bloodstream to screen for certain chromosomal conditions in pregnancy.
What conditions does the Harmony NIPT screen for?
The test primarily screens for:
-
Down syndrome (Trisomy 21)
-
Edwards syndrome (Trisomy 18)
-
Patau syndrome (Trisomy 13)
These are the most common chromosomal conditions screened during pregnancy.
What do these conditions mean?
-
Down syndrome (Trisomy 21) may be associated with learning difficulties, congenital heart defects, and other medical conditions.
-
Edwards syndrome (Trisomy 18) and Patau syndrome (Trisomy 13) are severe conditions linked to high miscarriage rates and serious birth defects. Most affected babies do not survive beyond infancy.
When can the Harmony test be done?
The test can be performed from 10 weeks of pregnancy onwards, making it an early screening option.
How is Harmony different from standard NHS screening?
Unlike traditional screening, which combines blood markers and ultrasound measurements, Harmony analyses fetal DNA directly, making it more accurate for detecting Trisomy 21, 18, and 13.
Can the test tell my baby’s sex?
Yes. With optional X and Y chromosome analysis, the test can determine fetal sex with over 99% accuracy.
-
This option is also available for twin pregnancies
-
In twin pregnancies, a female result applies to both babies; a male result indicates one or both babies are male
Can the test screen for sex chromosome conditions?
Yes, as an optional extra, the test can assess the risk of sex chromosome conditions such as:
This option will be discussed during your appointment. Please note that sex chromosome screening is not available for twin pregnancies.
What does a HIGH-RISK result mean?
A high-risk result means there is a strong likelihood that the fetus may have a chromosomal condition.
-
Detection rates exceed 99% for Trisomy 21, 98% for Trisomy 18, and around 80% for Trisomy 13
-
A high-risk result does not confirm a diagnosis
-
Follow-up diagnostic tests, such as CVS or amniocentesi,s are recommended to confirm the result
What does a LOW-RISK result mean?
A low-risk result means it is unlikely that the fetus has Trisomy 21, 18, or 13. While no screening test is 100% accurate, the likelihood of these conditions is very low. Routine pregnancy scans should continue as normal.
How long do results take, and can the test fail?
Results are usually available within 7 working days.
In some cases, the test may fail due to low fetal DNA levels (below 4%). This can occur due to:
- Early testing
- High maternal BMI
- Sampling issues
- Certain fetal conditions
If this happens, a repeat blood test is offered at no extra cost.
Is the Harmony test safe for my pregnancy?
Yes. The test is non-invasive and involves only a blood sample from the mother’s arm. There is no risk of miscarriage, unlike invasive tests such as CVS or amniocentesis.
Is the Harmony NIPT available on the NHS?
The NHS currently offers only combined or quadruple screening tests, and invasive testing is offered if those results are high risk.
NIPT is not routinely available on the NHS due to cost, which is why many parents choose private testing for greater accuracy and peace of mind.
