2. The selection of examinees is always made on the basis of work environment monitoring, often resulting in the underdetection of exposed workers.
3. Even if the test items are properly selected according to the principles of occupational medicine, further review is required in the light of recent advances in the pathogenesis as well as early changes of occupational diseases and epidemiologic principles.
4. The criteria for the classfication of health levels are to be reviewed on the basis of clinical epidemiology.
