Abstract: A mobile application (mobile app) runs on a mobile device to virtually establish, coordinate, and maintain chain of custody of laboratory sample specimens so as to facilitate inventory management, custodianship, notifications, query, resulting, and other duties of sample management. This is also known as virtual accessioning. Users navigate through various user interface screens to log information, manage inventory, plan/track shipments, create notifications, and other functions of sample management. The mobile application can be customized to integrate with other systems such as clinical trial management systems, sample storage databases, and laboratory information management systems. The web-interface acts as the dashboard and data aggregator for end-users. The mobile application acts solely as a tool for assisting the sample and/or result management process.
