| Abstract: | * For detection of errors where the standard deviation is wide compared to clinical requirements, consider use of the Capability Index (Cps). * Cps is defined as 'Allowable Limit of Error divided by the standard deviation of between-batch QC measurement'. * 'Capable' assays have Cps >4 compared with 'incapable' ones with Cps <4. * Capability of an analyte can be used to optimise the amount of quality control (QC) required and still maintain appropriate error detection. * For EQA material, Cps can be used for continuously monitoring individual analytes, comparing laboratory performance with peers and comparison with industry-wide performance. * The capability approach can result in reducing the number of QCs run per day, reducing costs as well as significantly improving the performance of a number of assays. |
