The Central England Haemato-Oncology and Oncology Research Biobank (CEHRB) predominantly stores excess material from haemato-oncology and oncology samples referred for diagnostic testing and disease monitoring at the West Midlands Regional Genetics Laboratory (WMRGL). Haemato-oncology samples are stored at presentation and throughout the disease course, including at remission and relapse. In addition CEHRB stores haemato-oncology and oncology samples which are specifically taken for the biobank, usually in response to a specific project.
