New approach for prenatal testing
Testing of cell-free fetal DNA in maternal plasma is a screening test for Down syndrome and other trisomies which is now available in Australia. It has garnered high levels of public interest and expectation.
However, although this form of testing appears to show great promise, there are currently no Australian guidelines defining its place in prenatal assessment.
In this article, we explore the methodology of non-invasive prenatal testing (NIPT), its uses and limitations, and give recommendations as to when, and in whom, it is best used.
