[Evidence-based use of clinical biochemistry].
Evidence-based use of clinical biochemistry integrates into clinical decision-making the best research evidence with the clinical expertise of the physician and the expectations and concerns of the patient. The best research evidence for the clinical use of a biochemical test should be appraised in close collaboration between clinicians and specialists in clinical biochemistry, as familiarity with both the clinical problem and the analytical performance of the test is necessary. At present, it is difficult to ensure an evidence-based use of biochemical tests. More and methodologically better studies of the clinical value of biochemical tests are needed, and methods should be developed that make it possible to assess the results of such studies by systematic reviews and meta-analyses. Clinical biochemistry is an interdisciplinary specialty, and papers on the clinical value of biochemical tests are published in a vast number of journals of different clinical specialties as well as those of clinical biochemistry. It is thus almost impossible to keep abreast of the subject. The establishment of a system for literature surveillance focusing on methodologically sound studies of the clinical value of biochemical tests would be advantageous. Lastly, training and education on how to find and assess the existing evidence for the clinical use of biochemical tests are needed.
