Sigma metrics can be used to predict assay quality, allowing easy comparison of instrument quality and predicting which tests will require minimal quality control (QC) rules to monitor the performance of the method. A Six Sigma QC program can result in fewer controls and fewer QC failures for methods with a sigma metric of 5 or better. The higher the number of methods with a sigma metric of 5 or better, the lower the costs for reagents, supplies, and control material required to monitor the performance of the methods.
西格玛指标可用于预测检测质量，便于对仪器质量进行比较，并预测哪些检测将需要最少的质量控制（QC）规则来监测方法的性能。对于西格玛指标为5或更高的方法，六西格玛质量控制程序可减少质控品数量和质控失败次数。西格玛指标为5或更高的方法数量越多，监测这些方法性能所需的试剂、耗材和对照品成本就越低。
