Guidance from The Royal College of Pathologists and Institute of Biomedical Science recommends residual DNA remaining following completion of testing is stored for a minimum of 8 weeks. Current storage capacity allows retention of DNA for a minimum period of 3 years. Referred specimens (blocks/ unused slides) will be retained for 2 weeks after testing is complete before being returned to the referring pathology. Material is returned using sample tracking and confirmation of receipt is requested. If a specimen is required prior to test completion or within a specified time frame this should be clearly communicated to the service.
