NIPT (Non-Invasive Prenatal Test)

This is a new, non-invasive, pre-natal screening test to detect chromosomal disorders and sex chromosome disorders as well as the baby’s gender if requested.

The Chromosome disorders detected are commonly known as Down’s syndrome (Trisomy 21), Edward’s syndrome (Trisomy 18) and Patau’s syndrome (Trisomy 13). The Sex Chromosome disorders that can be detected are commonly known as Turner syndrome (XO), Klinefelter syndrome (XXY), Triple-X (XXX) and Jacob’s syndrome (XYY)

The baby’s gender is determined by the presence, or lack of, a Y chromosome in the mothers blood sample.

We currently offer Non-Invasive Prenatal Tests from 3 providers: Vision, IONA and Harmony.

All of the tests we offer measure the fetal DNA present in a sample of the mothers blood and are available from 10 weeks gestation. All of the tests can be requested for single and twin pregnancies, including IVF pregnancies and pregnancies where a donor egg has been used.

The chart below shows the differences between the 3 tests we offer. If you have any other questions or would like to make an appointment, please contact us and we will be happy to help.
