Periodically repeated multi-phasic health tests--a unique data source for detecting subject-specific normal ranges

When a comprehensive health check-up is repeated for the purpose of health control, the individual clinical data should be evaluated carefully by a proper normal range, which must be specific to each subject, if early detection of disease is a goal. The Perfect Liberty Health Control System, a health plan run on a membership basis, has been giving its periodic multi-phasic health tests to all of the 24 000 + members biannually since 1970. Studies concerning health parameter dynamics have been made on the data obtained and these are important to the new challenging field of clinical laboratory examinations. Other helpful aspects of this punctually repeated AMHTS (Automated Multi-phasic Health Testing) on a lifetime membership basis are also presented, such as cancer detection accuracy, protection from unnecessary X-ray exposure during examinations and a new form of physician's examination supported by current laboratory-data preview.
