[Laboratory tests in primary care medicine: pre-clinical, ambulatory screening test system on the basis of the patient's chief complaints in the initial diagnosis making].
We have explored the efficacious laboratory test system to be performed before the first medical contact with a physician on the basis of the patient's chief complaints and their abnormalities of the "essential laboratory tests" advocated by the Japan Society of Clinical Pathology by analyzing 2,625 complaints from 2,175 new patients visited the outpatient unit of Comprehensive Medicine, National Defense Medical College. The patients with complaints such as general fatigue, fever of unknown origin or reno-urinary symptoms showed higher abnormalities of these diagnostic tests than those in 750 patients performed these tests irrespective of the patient's chief complaints. However, complaints originated from neurological, gastro-intestinal, cardiovascular or respiratory diseases were not associated with abnormalities of these laboratory tests in the patients as compared to those in 750 patients mentioned above. These results indicate that (1) clinical usefulness of the "essential laboratory tests" are variable depending on the patients chief complaints and these tests are recommended for the patients with complaints such as general fatigue, fever of unknown origin or reno-urinary symptoms as pre-clinical ambulatory screening tests before history taking and physical examination to enable to make accurate initial diagnosis and subsequent efficacious medical approach and (2) test items should be selected depending on the patient's chief complaints.
