Abstract
Objective To investigate how to use the sigma value to chose the appropriate quality control rules for the blood cell analysis test project .Methods T he cumulative variation coefficient (CV) of quality control conducted in our hospital from January to December 2016 were collected as an estimate value of the in-accuracy of the measurement ;The date of Percentage difference of blood cell analysis test of external quality assessment of National Clinical Laboratory center in 2015 second and 2016 was took advantage of estimated value ,the TEa of the biological variation derivation is used as the standard ,according to the formula of sigma＝(TEa－|Bias|)/CV ,calculate the sigma value of each item .Use the Westgard sigma rule to select the appropriate quality control rules for the clinical laboratory′s blood cell analysis test .Results Using a perform-ance specification based on TEa of biological variation ,the sigma value of WBC was achieved 6σ quality level , the 13s rule was chosed (N＝3 ,R＝ 1) ,and the sigma value of the Hb was achieved 5σ quality level ,13s/2 of 32s/R4s was chosed (N＝3 ,R＝1).and the sigma value of the RBC ,PLT and HCT are all 4σ quality level ,13s/2 of 32s/R4s/31s were chosed (N＝3 ,R＝1).Conclusion Using the rule based on TEa of the Westgard sigma rule could help to chose the appropriate quality control rules and the number of each batch of quality control measurement value for test items of clinical laboratory quickly .关键词
