目的探讨Westgard多规则中2_(2S)规则在单一浓度质量控制中的应用条件。方法将2_(2S)规则适用范围拓展到单一浓度质控品的同批检测。结果 2_(2S)规则可以提高系统误差的检出率。结论 2_(2S)规则在使用单一浓度质控品时,应适用1个批次的2次检测,以提高系统误差检出的及时性。
Objective To explore the application conditions of 2_ (2S) rule in Westgard multi-rules in single-quality control. Methods The application of 2_ (2S) rules was extended to the same batch of single-quality control products. Results 2_ (2S) rule can improve the detection rate of systematic error. Conclusion 2 (2S) rules in the use of a single concentration of quality control should be applied to a batch of 2 tests to improve the system error detection timeliness.
