Abstract
In the clinical context of physical therapy, especially of risk management's standpoint, it is of paramount importance to evaluate clinical examination data. The series of our reviews will introduce physiological implications of the data as well as its relation to diseases, and clinical application to physical therapy. This time, we review general blood examinations, especially the examinations on blood cell components such as erythrocyte, hemoglobin, hematocrit value, leukocyte, erythrocyte sedimentation rate, platelet, and diseases that indicate abnormalilty of these data.
