Please call us on 0118 958 5050 to book an NIPT.
The NIPT (Non Invasive Pre-natal Test) looks at the baby’s DNA to detect chromosomal disorders, sex chromosome disorders and the baby’s gender if requested. They are available from 10 weeks. The first part of an NIPT is a Dating Scan to confirm gestation and viability. The second part of the test requires a sample of the mothers blood. One of our qualified phlebotomists will take your sample and send it to the lab to be tested.
The Chromosome disorders detected by an NIPT 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.
Both of the tests we offer measure the baby’s DNA present in a sample of the mothers blood and are available from 10 weeks gestation. Both 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 NIPTs 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 you.
