![]() If you are over 12 weeks, we suggest booking in for one of our advanced scans if you’d like anatomical details to be checked. The scan must be performed at least 2 weeks before the blood test, ideally on the same day. You will get a report, 2 pictures as well as a short video clip of the scan sent to you via sms or email. Harmony does not screen for potential chromosomal or genetic. This is a simple diagnostic scan just to obtain the above information. The Harmony Prenatal Test is a non-invasive prenatal test (NIPT) based on cell-free DNA analysis. Fetal fraction increases as gestational age increases thereby reducing the likelihood of receiving an inconclusive result.Ī scan is performed in conjunction with the blood test to confirm viability, gestational dating and number of fetuses. If you fall into one of the above categories, we recommend waiting until 11 or 12 weeks (or later) to perform your NIPT. This can cause unnecessary concern and the hassle of repeating the test. TEST FAILURES / RETESTS: While we get results back on most of our patients, please note that there is an increased likelihood of an inconclusive result on mothers weighing over 85kg, mothers using blood thinners such as Clexane, IVF pregnancies, and twin pregnancies. Please also note that these tests are specific for the above mentioned conditions and they do not rule out all fetal and other pregnancy related abnormalities. So in the event of a high risk result we recommend amniocentesis or CVS. Please note that if the results of the test show high risk for one of the conditions it does not mean that the fetus definitely has the condition, although it is highly likely. More importantly, the number of women who are required to have invasive testing (amniocentesis or CVS) after undergoing NIPT is <1%. Accuracy for detecting other sex chromosome anomalies varies by condition. In addition to this the fetus’s sex can be determined with >99% accuracy. This simple blood test must be performed in conjunction with a dating ultrasound. It is a screening test for Down syndrome (trisomy 21) and other conditions such as Edward’s syndrome and Patau syndrome (trisomies 18 and 13), as well as X and Y chromosome conditions. Non-invasive prenatal testing (Nipt) analyses cell-free fetal DNA circulating in the mother’s blood. The Ultrasound Suite along with the Bray Women’s Health Centre offer PrenatalSAFE and Panorama non-invasive prenatal testing. We are now using PrenatalSAFE instead, as it offers a faster turnaround time and a lower failure rate than Harmony. Please note we no longer perform HARMONY. Please book at least 2-3 weeks in advance to avoid potentially long waiting lists. The ultrasound element can be performed in any of our three clinics. **Īll blood tests are performed in Bray Women’s Health Centre. This may be part of the excess of your insurance though.**Please note: NIPT testing can ONLY be booked by phoning Bray Women’s Health Centre on. If you have an elevated chance for a baby with Downs-, Edwards- and Pataus syndrome you can have NIPT, in the TRIDENT-1 study, covered by your health insurance. The payment for NIPT has to be done online at This site also contains information frequently asked questions about the payment. The result of your NIPT will be discussed with you by your midwife or obstetrician. Also your due date has to have been determined by a due date scan at at least 10+5 weeks of pregnancy. NIPT must have been paid before the drawing of your blood. The blood analysis for NIPT can be performed from the 11th week of pregnancy at the SALT laboratory. After asking all the questions you have and having heard the different aspects of the screening process you will decide whether to have the screening performed or not. I don’t know if there are any differences aside from when you can test though. Harmony is done at 10 weeks and Paranoma is at 9 I think. ![]() If you want more information you will get a seperate consultation to talk about this screening. NIPT stands for non invasive prenatal testing so that includes both harmony and panorama. If you do not want this information it means that you choose not to test your child for the mentioned syndromes. First appointment with your midwife or obstetricianĪt your first visit with your midwife she will ask you whether you want information about the screening for Downs-, Edwards- and Pataus syndrome. Information about prenatal screening for Downs-, Edwards- and Pataus syndrome, which includes information about NIPT, can be found on This site is in Dutch but you can download an english, and many other languages, version of the information booklet on this site. ![]() NIPT is currently offered in the Netherlands within the TRIDENT study. NIPT (Non Invasive Prenatal Test) is a new test which analyses fetal DNA in maternal blood to check for Down-, Edwards- and Patausyndrome.
