title: [Informed consent for the use of the remaining portion of laboratory specimens for education, research, and quality control of laboratory tests].
abstract: The remaining portion of a laboratory specimen is usually used for education, research, and quality control of laboratory tests in hospitals, but informed consent has not been obtained because of the high volume of patients who undergo laboratory tests. However, patients must be informed in some manner. Therefore, we decided to inform patients that any remaining specimen would be used for various purposes by placing such a notice on walls in the central clinical laboratory and hospital lobby. We then obtained a signature on a dissent document, instead of a consent document, from any patient who dissented from such use. This indirect process for obtaining informed consent was approved by the ethics committee of Osaka University Medical School. The number of dissent documents sent in to the director was 54 of about 400,000 patients who underwent laboratory tests over the last 3 years, and there was no complaint against this "informed consent process".
