One tertiary Australian hospital has noted a 20% decline in invasive antenatal procedures i.e. amniocentesis or chorionic villus biopsy. This is the direct result of the cell free DNA testing on the mother’s blood sample, which is non-invasive prenatal test that has become more widely available over the last five years. This is reassuring for mothers and has achieved a considerable improvement in the standard of care for women and their unborn babies.
