Recruitment for this study has now closed.

Will I find out the results of the research using my tissue or blood?

The results of research done with your tissue or blood are not likely to be available for several years. This is because research can take a long time and must use samples from many people before the results are known. We will not be able to give you the individual results from your samples but everyone who takes part in the OPAL Study will be sent regular updates to let you know how the study is going. You can also contact the Study Team at any time if you have any questions about the study. In exceptional circumstances, when we believe that the information we have will be very important for your health or that of your close relatives, we may contact you. In this situation we would advise you to seek help from an appropriate health professional.

Can I withdraw from the study?

You can withdraw from the study at any time and this will in no way affect your medical treatment in the future. Also, if you decide now that your tissue and blood can be kept for research, you can still change your mind later. Just contact us to let us know you want to withdraw.
If you choose to withdraw, we will discuss with you whether you wish your information and/or blood and tissue samples to be destroyed or whether we may continue to use them.
