The clinical value of many laboratory tests has frequently been queried. A short questionnaire was attached to individual microbiology reports issued to general practitioners in Bradford for an eight week period. Of the 2386 questionnaires sent out 1847 (77%) were returned. The general practitioners indicated that 34% of reports gave unexpected findings, 28% resulted in a change of therapy and most of the investigations (83%) were seen as beneficial to the patients. The majority of the specimens (56%) were mid-stream urine samples of which 77% gave negative findings. This study indicates that conventional microbiology test results are more valuable in general practice than previous hospital based surveys might suggest. Alternative strategies for investigation to reduce the number of tests of low value are discussed.
许多实验室检查的临床价值常常受到质疑。在为期八周的时间里，一份简短的调查问卷被附在发给布拉德福德全科医生的每份微生物学报告上。在发出的2386份调查问卷中，有1847份（77%）被收回。全科医生表示，34%的报告给出了意外发现，28%导致了治疗方案的改变，并且大多数检查（83%）被认为对患者有益。大多数标本（56%）是中段尿样本，其中77%的结果为阴性。这项研究表明，在全科医疗中，传统微生物学检查结果比以往基于医院的调查所显示的更有价值。文中还讨论了减少低价值检查数量的替代调查策略。
