NIPTHarmony Test

Harmony® Test is a non-invasive method for the detection of the fetal trisomies in the unborn child, based on the analysis of the genetic material (fetal DNA) that circulates in the mother’s blood.

The Harmony® Test is an early and reliable prenatal screening test for the mother’s blood after completion of the 10th week of gestation.

In chromosomally health fetuses, the genetic information is stored in 23 pairs of chromosomes. A trisomy is a chromosomal disorder in which a certain chromosome occurs three times instead of twice.

Trisomy 21 is the most common form of a chromosomal disorder at birth. It occurs in approximately one out of every 830 newborns. The probability of its occurrence depends to a large extent on the age of the mother. A trisomy 21 leads to “Down syndrome”, which can cause mild to moderate mental disability as well as other illnesses such as congenital heart diseases. The average life expectancy of affected persons today is around 60 years.

Trisomy 18 causes “Edwards syndrome”. This trisomy appears in approximately one out of every 5,000 newborns. Trisomy 13 (“Patau syndrome”) affects approximately one out of every 16,000 newborns. Both trisomies are associated with a high rate of miscarriage. Affected children suffer from several disorders simultaneously, including serious heart diseases. The mean life expectancy of babies affected by trisomy 18 or 13 is only a few months and they rarely survive their first year of life.

HarmonyCompared To Other Prenatal Testing Methods

The Harmony® Test allows the detection of the most common chromosomal disorders in the unborn child by taking a sample of the mother’s blood.

Unlike invasive methods, the Harmony® Test carries no risk of miscarriage.

Especially for a fetal trisomy 21, the informative value of the Harmony® Test is far higher than other methods such as first trimester screening (ultrasound + hormone analysis)

NIPTBiological Background

Fetal cell free DNA is released from the placenta into the maternal bloodstream. From gestational age 10+0 the amount of fetal DNA usually is sufficient for analysis.

 

What is cell-free fetal DNA?

DNA (genetic material) passes from the placenta to the mother’s blood and can be analysed for chromosomal disorders using the Harmony® Test. Although highly accurate, the Harmony® Test still must be regarded as a screening test in which false positive and false negative cases can occur.

Performance appraisal of the Harmony Test

The Harmony® Test is an non-invasive test to detect fetal trisomies 21, 18, 13, and sex chromosomal disorders. The test can be performed after the 10th week of pregnancy and has no risk of a procedure – related miscarriage.

High Detection Rate – 99.3% detection rate for trisomy 21 in published studies

No other NIPT method has been investigated as intensely in clinical studies as the Harmony® Test. If one summarises the most important studies published, the Harmony® Test has a detection rate of 99.3% for trisomy 21 (trisomy 18: 97.4%, trisomy 13: 93.8%)

Low False Positive Rate – Only 0.04% trisomy 21

In a large interdisciplinary analysis exact data on the false positive rate of the Harmony® Test could be determined in an unselected patient collective. The false positive rate for more than 23:155 pregnant women for trisomy 21 is 0.04% (trisomy 13 and trisomy 18: 0.02% each) and thus about 125 times lower than in the first trimester screening which had a false positive rate of about 5%.

High Qualified Teams of Physicians – Specialists in human genetics, laboratory medicine, and obstetrics

Cenata comprises a team of qualified doctors, including specialists in human genetics, laboratory medicine, and obstetrics and gynaecology, for diagnosis and counselling.

Applications of the Harmony Test

The Harmony® Test can be applied for all singleton or twin pregnancies, irrespective of the manner of conception or origin of the ovum. Cenata must be informed about an egg donation when the test is requested. If an egg donation is kept secret, the Harmony® Test is not able to deliver a result. In case of more than two fetuses or a vanishing twin, the Harmony® Test cannot be performed.

Rhesus

Rhesus

Determination of the fetal Rhesus factor from maternal blood
You may already know your blood type, for example if you are a blood donor. Your blood type is also determined as part of maternity care at the beginning of your pregnancy to check if you have the blood group factor RhD-negative (“Rhesus-negative”). About 17% of all women are RhD-negative.
