The nutrition support team (NST) in our hospital not only develops clinical nutritional methods in inpatients but also performs the entire nutritional management including nutritional prescription in consultation with the physician in charge. In NST activity, clinical technologists have opportunities to report information on laboratory examination values obtained in daily work and make proposals. These opportunities are useful not only for enhancing the awareness of technologists who have focused on specific duties but also for training medical technologists. We hope that medical technologists participate in NST activity as full medical staff members in many institutions.
