Combining information from your medical records, questionnaire data, and DNA provides a comprehensive overview for researchers to use in a wide range of investigations. We will only access relevant sections of your medical records that will be helpful to the goals of the GLAD study and the research projects approved by the NIHR BioResource Steering Committee. For example, we will request information on the details of your history with anxiety and/or depression and how well you responded to treatment. Unless strictly necessary, all information obtained from your medical records will be given a pseudonymised (coded) ID, kept strictly confidential and will be stored separately from your personal information (e.g. name, date of birth).
