卫生微生物检验结果是卫生质量评价的主要指标之一。多年来，许多微生物检验工作者在致力提高检验质量和实验室间的可比性方面做出了很多成绩，但对影响微生物检测指标的最基础因素稀释液的研究甚少，到目前为止未见报道。我们通过几十年的观察，发现带有指示剂的液体培养基高 Hygienic microbiological test results are one of the main indicators of health quality evaluation. Over the years, many microbiological laboratory workers have made many achievements in their efforts to improve the quality of testing and the comparability among laboratories. However, little research has been done on the diluents, the most basic factor affecting the detection indexes of micro-organisms, and so far no reports have been reported . Through decades of observation, we found high liquid medium with indicator
