Abstract:
【Objective】 To help quality control laboratory of blood station select suitable internal quality control rules using Westgard sigma rules. 【Methods】 The accumulated coefficient of variation of internal quality control was used as the measurement imprecision in quality control laboratory of blood station, and the bias of the results of EQA in 2020 was regarded as Bias. The allowable total error (TEa) of WS/T406-2012 was used as the evaluation index to calculate the σvalue of laboratory blood testing items to select reasonable and feasible quality control rules using the Westgard sigma rule. 【Results】 The average σvalues of total protein in the three national EQAS were 14.2, 8.7 and 9.6, respectively. The average σvalues of fibrinogen in two national EQAS were 3.6 and 4.1. The average σvalues of Plt counts and MCHC were <4 and >3, and those of other items were more than 6 in two national EQAS. 【Conclusion】 The rule of 13s, 13s/22s/R4s/41s/

should be used in total protein, fibrinogen and whole blood cell count testing, respectively, by Westgard sigma rule, which can effectively help the blood quality control laboratory select appropriate quality control rules.
