Introduction to Laboratory Medicine and Evidence-Based Laboratory Medicine... 

Clinical Chemistry, Laboratory Medicine, and Evidence-Based Laboratory Medicine In this chapter, we review the new influences on clinical chemistry and laboratory medicine from the fields of cfinical epidemiology and evidence-based medicine (EBM). Cfinical epidemiologists have developed study designs to quantify the diagnostic accuracy of the tests developed in laboratory medicine, and study methods to evaluate the effect and value of laboratory testing in healthcare. Practitioners of EBM focus on use of the best available evidence from such well-designed studies in the care of individual patients. EBM rephrases problems in the clinical care of patients as structured clinical questions, looks for the available evidence, evaluates the quality of cfinical studies, evaluates the clinical implications of the results, and provides tools to help clinicians optimally use those results in the care of individual patients. 

This brief section contains a definition of EBM and describes its goals and key practices. Following this, evidence-based laboratory medicine will be addressed.

APPLYING THE PRINCIPLES OF EVIDENCE-BASED LABORATORY MEDICINE IN ROUTINE PRACTICE... 

It is hopefully clear from the foregoing discussion that the principles of evidence-based laboratory medicine can underpin the way in which laboratory medicine is practiced, from the discovery of a new diagnostic test through to its application in routine patient care. The principles provide the logic on which aU of the elements of practice are founded. The tools of evidence-based laboratory medicine provide the means of delivering the highest quality of service in meeting the needs of patients and the healthcare professionals who serve them. The application of evidence-based practice is far more complex in the case of laboratory medicine than in the major area in which such principles have previously been applied, namely the pharmaceutical intervention.
