SAFET21 / NIPS non invasive prenatal screening from 10 weeks

Developed by the Chinese University of Hong Kong, this is a non-invasive DNA blood test to screen for chromosomal abnormalities. These include Down syndrome (T 21), Edwards syndrome (T 18), and Patau syndrome (T 13) and many more.

By drawing blood from the mother, the test detects if there are increased levels of certain DNA molecules which the baby releases into the mother's blood circulation. The test is around 99.6 percent accurate.  


SafeT21  is not yet available in the public healthcare but is an optional test for those that choose this over the Nuchal fold screening or the more invasive amniocentesis. If you are unsure which option is most appropriate for you, the early midwife or doctor's consultation is perfect to discuss this.


The test can be performed from 10 weeks, with no upper limit and can also be performed for twin pregnancies. The results of this blood tests are usually back within 3 - 5 days.


If this is done as a part of a 12 week scan you need to add consultation fee for the doctor, if as a part of a routine checkup you need to add midwives consultation fee.
