影响微生物检验室内质量控制的因素及对策分析

Objective To investigate the factors influencing indoor quality control in microbial testing and propose corresponding countermeasures. Methods A total of 120 samples subjected to microbial testing from February 2024 to November 2025 were randomly divided into two groups, with 60 samples in each group. The control group adopted conventional quality control methods, while the observation group implemented improved measures targeting the influencing factors in addition to conventional methods. Key indicators such as testing error rate, report timeliness rate, and result accuracy rate were compared between the two groups. Results The factors influencing quality control in microbiological testing laboratories include non-standard personnel operations(37.50%), inadequate management of equipment and reagents(31.25%), deviations in testing procedures(25.00%), and insufficient environmental and management controls(6.25%). The control group exhibited a testing error rate of 12/60(20.00%), report timeliness rate of 43/60(71.67%), and result accuracy rate of 48/60(80.00%). The observation group showed a testing error rate of 3/60(5.00%), report timeliness rate of 55/60(91.67%), and result accuracy rate of 57/60(95.00%). All differences between the two groups were statistically significant(P<0.05). Conclusion Identifying the factors affecting indoor quality control in microbial testing and implementing effective countermeasures can significantly reduce testing error rates, improve report timeliness and result accuracy rates, thereby enhancing the overall quality of microbial testing.
