Routine laboratory tests are the most frequently performed among clinical laboratory tests, and they can provide important information for the diagnosis and treatment of patients. They are more useful when several data are combined to interpret the pathophysiological state of a patient. Changes of routine laboratory data are important even when they are within their reference ranges, and they sometimes show a more detailed condition of the patient. In this symposium, we demonstrated our method at Shinshu University Hospital, involving the evaluation of 13 conditions of the whole body or each organ by simultaneously interpreting some to several laboratory data.
