The Clinical Lab Scientist performs routine and problem-solving testing procedures in the Transfusion Service, using both manual methods and automated instruments. The role includes accurately reviewing, validating, entering, and reporting results in the laboratory information system (LIS), investigating transfusion reactions and unexpected results, and following established procedures and quality-control requirements. The scientist must be able to work in a high-volume setting and independently exercise sound judgment. The position also involves supporting blood product inventory and orders, including emergency release and massive transfusion protocol products, and handling organ and vessel inventory and allocation processes. The Clinical Lab Scientist communicates effectively with hospital personnel and coworkers, operates and troubleshoots laboratory equipment, performs assigned maintenance, documents work and incidents, and assists with training, special studies, and other projects. The role requires adherence to infection-control and personal-protection practices and to UCSF Medical Center and Clinical Labs policies.
