A small number of participants (10 - 20% percent) will also be invited to provide a blood sample, after they have completed the questionnaires and saliva sample. This sample will allow us to examine more than just DNA, such as the circulating hormones and vitamin and mineral levels in the blood.
If we need to get a blood sample from you, we will invite you via email, then follow up with a phone call to ask you to visit your nearest pathology collection centre. You will not incur any costs for providing this sample.
To learn more about the blood sample, please read the Blood Sample FAQs.
