How does the NIPT test differ from an amniocentesis test?

It is important to note that the NIPT test is not a direct replacement for the amniocentesis test

However, what this test does offer mums-to-be is the opportunity to potentially negate the need for an amniocentesis, thus offering a much safer screening option for certain conditions.

The NIPT is a quick non-invasive screening test that simply involves one blood draw. Whilst a woman is pregnant, their baby’s DNA circulates in the woman’s blood stream, meaning that we are able to test for the three main conditions with a 99.8% accuracy rate.The NIPT test will screen for the same three conditions as the amniocentesis; Down’s syndrome, Patau’s syndrome and Edward’s syndrome. However it will also offer parents the opportunity to accurately discover the gender of their baby from as early as 10 weeks pregnant.Historically, a simple blood draw such as Vision was not freely available and mothers that were considered to be high risk, were advised to have an amniocentesis. This unfortunately is considered to be a high risk procedure and may lead to miscarriage.Whilst the results of the NIPT test may still indicate the need for some women to progress on to the amniocentesis, it will also substantially lower the number of women having this procedure unnecessarily.
