Overview

All pregnant women in Australia are offered voluntary prenatal screening for fetal chromosome conditions to learn more about their health of their unborn baby.

The Reproductive Epidemiology group has led research in this field for many years, publishing scientific papers and reports on prenatal testing that have informed Australian clinical practice guidelines and health policy.

Our research

Annual Report on Prenatal Diagnostic testing in Victoria

This publication from the Victorian Prenatal Diagnosis Database (VPDD) analyses state-wide trends in fetal chromosome testing every year. The VPDD is a longstanding collaboration between the Reproductive Epidemiology group, the Victorian Clinical Genetics Services, Monash Pathology, and formerly, Melbourne Pathology and Australian Clinical Laboratories.

A comprehensive description of number of tests, indications for testing, and test results are provided in each publicly available report.

Perinatal Record Linkage (PeRL) study

Women’s choices of prenatal screening and diagnostic pathways have increased in complexity since introducing new technologies, such as cell-free DNA-based screening (noninvasive prenatal testing) and chromosomal microarrays. In the PeRL study, we performed individual record-linkage of women undergoing screening and diagnostic testing to understand the utilization of prenatal testing in Victoria, and to analyse the performance of different screening strategies. The federal government has used our research outputs to assess Medicare funding for prenatal screening.

Your Choice Prenatal Screening - Your Choice

This free online decision-aid is a web-based app developed in collaboration with James Cook University and Curve Tomorrow. It is designed to help women consider their preferences and options for prenatal testing so that they can have an informed discussion with their health care provider.
