80,000 Australians have registered to take part in the study!

Of these, over 51,000 participants have submitted their questionnaire and saliva sample.

We are nearing the end of our initial data collection stage for the study. Participants are no longer able to login to complete the questionnaires. Those who have been sent a saliva sample are enouraged to return it by the end of the year, for inclusion in our research. 

If you have any questions, please contact us.

Our goal was to achieve 50,000 completed questionnaires and saliva samples. Thank you for helping us to reach this goal. 

The ABC Study includes people aged 40 -74 years.
