[Acquisition of accreditation ISO 15189 and view of the future--case of a private college].

We received ISO 15189 accreditation (International Organization for Standardization 15189) in 2009. Several effects from the subjective points are shown below, 1. The reliability of the test results has improved. 2. Skill or knowledge level of staff has improved. 3. Internal recognition has improved. 4. Procedures to prevent accidents have been enforced. 5. Management system has improved. 6. Effective management tool for the manager. In addition to high costs for qualification and maintenance, extensive human resources are required to prepare documents. We need to make further efforts to aim at better cost-effectiveness.
