A new, DNA-based technology

NIPT is a DNA-based blood screening test that measures the risk of Down syndrome (trisomy 21) from as early as 10 weeks in pregnancy.

When you are pregnant, your blood contains fragments of your baby's DNA.
Harmony Prenatal Test analyses DNA in a sample of your blood to predict the risk of Down syndrome (trisomy 21) and certain other genetic conditions.

NIPT Test is more accurate than traditional Down syndrome blood tests, meaning it is much less likely to give a false-positive result compared to traditional tests, such as the first trimester screening test. Reducing the chances that your doctor would recommend follow-up diagnostic testing, such as amniocentesis.

In addition, NIPT can assess fetal sex. This is optional (no additional cost).

NIPT does not screen for non-chromosome disorders, familial mutations, malformations, fetal growth or fetal viability.

Who is the NIPT test suitable for?

NIPT can be ordered by healthcare professionals for women with pregnancies of at least10 weeks' gestational age. This test can be requested for any singleton or twin pregnancy, including those conceived naturally or by IVF using the patient's own egg or a donor egg.

Note that, in twin pregnancies, sex chromosome (X and Y) analysis can determine fetal sex but not sex chromosome conditions. This test is not suitable in the case of a vanishing twin. The sex of twins will be reported as one result. If male, one or both of the twins will be male. If female, both twins will be female.

The test does not assess risk for mosaicism, partial trisomies or translocations.


Three steps to accurate Trisomy screening

1. Early Pregnancy Scan
2. Blood Test
3. Results In 2-5 Working Days Once Lab Is In Receipt Of Bloods

Exceptional Performance

NIPT is validated for pregnant women of any age or risk categories and trusted by clinicians worldwide. AS EARLY AS 10 WEEKS, the NIPT Prenatal Test screens for the risk of trisomy 21(Down syndrome), 18 (Edward syndrome) and 13 (Patau syndrome).

Three steps to clear answers

While other commonly used tests for Down syndrome are performed later in pregnancy and require multiple clinic visits, NIPT delivers clear answers as early as the first trimester with a single blood draw.

1. A maternal blood sample is taken at week ten of pregnancy, or later.

2. DNA in the sample is analysed using proprietary The VeriSeq NIPT Solution v2.

3. Test results are reported to Numi Scan North London in 5 business days or less.

Your Results
The test result will give you a clear answer about the risk to your pregnancy of having any of the genetic conditions included in the test. All results will be given to you by Numi Scan North London You should continue with your usual scan appointments

When do I expect to get the results?

The results from the test will usually be available within 5 days and we will notify you as soon as we receive them by email.

3 out of 100 women will require a repeat test. We receive a result in approximately two thirds of these samples. Patients will not be charged if we are unable to obtain a result.

What would the results show?

If the NIPT test shows that there is a high risk that the fetus has trisomy 21 or 18 or 13 it does not mean that the fetus definitely has one of these defects. If you want to be certain if the fetus has one of these defects you should have CVS or amnio.
If the Harmony test shows that there is a low risk (less than 1 in 10,000) that the fetus has trisomy 21 or 18 or 13 it is unlikely that the fetus has one of these defects.


Are there problems this test will not detect?

The NIPT test does not provide information on physical defects, such as heart or brain abnormalities and spina bifida, or fetal growth. It is therefore advisable that you still have your NHS ultrasound scans at 11-13 weeks and at 20-22 weeks to examine the fetal anatomy and at 30-32 weeks to examine the fetal growth, if needed.

The VeriSeq NIPT Solution v2 is not validated for use in pregnancies with more than two fetuses, fetal demise, mosaicism, partial chromosome aneuploidy, triploidy, translocations, maternal aneuploidy, transplant or malignancy. VeriSeq NIPT Solution v2 does not detect neural tube defects. Certain rare biological conditions may also affect the accuracy of the test.

For twin pregnancies, HIGH PROBABILITY test results apply to at least one fetus; male test results apply to one or both fetuses; female test results apply to both fetuses. Due to the limitations of the test, inaccurate results are possible.

A LOW PROBABILITY result does not guarantee that a fetus is unaffected by a chromosomal or genetic condition. Some non-aneuploid fetuses may have HIGH PROBABILITY results. In cases of HIGH PROBABILITY results and/or other clinical indications of a chromosomal condition, confirmatory testing is necessary for diagnosis.
