[Evidence-based laboratory medicine--a new trend in laboratory medicine].

The most important target of "evidence-based laboratory medicine(EBLM)", based on the fundamental concept of evidence-based medicine(EBM) is to improve appropriate, effective utilization of laboratory tests through close communication between clinical laboratories and clinicians. It is mandatory for clinicians to know of analytical uncertainty for better utilization of laboratory tests in clinical practice. Furthermore, the improvement of clinical utilization and interpretation of laboratory tests can be expected by supplying the evidences obtained through systematic reviewing or meta-analysis of laboratory tests. In order to pursue these purposes, closer communication and cooperation between laboratories and clinicians are important to obtain an effective consensus. Clinical laboratory must work together with interested clinician(s) for systematic review of laboratory tests. Construction of the ways of better laboratory-clinician communication should be an important paradigm for EBLM which will be an important factor for new revolution of laboratory medicine in future.
