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 would like to get a blood sample from you, we will invite you via email, allowing you to select the collection centre that is the most convenient for you. You will not incur any costs for providing this sample.
To learn more about the blood sample, please read the Blood Sample FAQs.
