Harmony Test / NIPT

When can I have the Harmony test?

Harmony test / NIPT (which means non-invasive prenatal testing), provides complete peace of mind and is offered from 10 weeks during pregnancy by Mr Pran Pandya BSc MBBS MD FRCOG, consultant in Fetal Medicine.

The test analyses fragments of the fetal DNA from a blood sample taken from the mother.

Why have a Harmony test / NIPT?
The purpose of the Harmony test /NIPT is to analyses cell free DNA in maternal blood (from the mother) to give a strong indication of whether the baby is at high or low chance of having trisomy 21 (Down syndrome), trisomy 18 (Edwards syndrome) or trisomy 13 (Patau syndrome).

The test identifies 99%, but not all, of the babies with trisomy 21, 98% of babies with trisomy 18 and 90% of babies with trisomy 13.

What does the Harmony test / NIPT test for?

The test is performed to check for common chromosomal abnormalities such as:

  • T21 (Down’s syndrome)
  • T13 (Patau’s syndrome)
  • T18 (Edward’s syndrome)

In addition, this test can also detect certain specific and known genetic conditions as well as fetal sex.

How long does it take to get the results?

The results will be available to you within 7-10 days.

What would the test results tell me?
It is important to note that if your Harmony test shows that there is a high chance that the baby has trisomy 21 or 18 or 13, it does not mean that the baby definitely has one of these conditions.

If you want to be certain if the baby has one of these conditions you should have CVS or amnio.

If your Harmony test result shows that there is a low chance (less than 1 in 10,000) that the baby has trisomy 21 or 18 or 13 it is unlikely that the baby has one of these conditions.
