Excerpt
For a clinical laboratory to serve any real purpose (1) the results of tests from that laboratory must be correct, (2) the tests themselves must be relevant for diagnosis and clinical care of patients and for health screening and epidemiological studies, and (3) the laboratory must be efficient, effective and as economical as possible without sacrificing its standards. To achieve these objectives of good laboratory practice requires skilled management with critical supervision of the work of the laboratory which must include a quality assurance programme.
