Taking part is entirely voluntary and you can change your mind at any time. You do not need to give a reason. If you would like to withdraw from the project, we would ask you to contact us by emailing firstname.lastname@example.org or calling on 0207 848 1638 or FREEPHONE 0800 634 4504 so we can register your withdrawal on our systems and get any feedback you may have of using the GLAD Study.
If you request it, we will remove your data from our electronic databases. You can also choose whether you would like your saliva sample to remain as an anonymised sample in the BioResource or whether you would like it to be destroyed.
