The collection of blood samples is one of the most essential procedures in laboratory examinations for the clinical diagnosis of patients. However, it is not always easy to carry out the procedure smoothly. At the Division of Clinical Laboratory in Yamagata University Hospital, we have tried to employ the best way to collect blood samples without any troubles or complaints. However, there were some complaints made by patients over several years, and one of these was that the waiting time for patients was too long. Therefore, we established a new system: all medical technologists joined the program and one took charge of collecting blood samples for 30 min, and then another technologist took over. The system was important for medical technologists since the duty allocation was impartial, and their routine work was not disturbed. We are proud of this newly-developed 30-min turn in collecting blood samples in our hospital.
