17 Oct 2017 In this context, the sigma metric of an assay is based on the precision (CV%) and decision levels (Xc), and other metrics (e.g. AMR, reference intervals) in Most method validation studies use a comparison of field methods rather normalized operational process specification (OPSpec) charts to clearly 19 Feb 2020 The Six Sigma methods are usually applied when the outcome of the process parameters on a Sigma Scale by calculating the sigma metrics for individual parameters and to follow covering the medical decision points.

The calculated Sigma-metrics and the Normalized Six Sigma Method Decision chart showed a majority of methods (48 out of 53, > 90%) on the Alinity ci system encompassing chemistry, immunoassay and electrolytes performed at Five Sigma (Excellent) or Six Sigma (World Class) quality. Print the Normalized Method Decision Chart. Manually plot your normalized operating point using the coordinates obtained from the calculator. Judge performance on the basis of the location of your operating point. Imprecision (CV) is the x-axis. This is a normalized Method Decision chart, which means multiple analytes with different TEa’s can be displayed on a single chart. This particular chart plots the performance of 32 biochemistry methods from the laboratory of Bumrungrad International Hospital in Bangkok, Thailand (38, 39). The majority of plotted performance falls in the World Class or Six Sigma zone, with 3 assays in the Excellent or Five Sigma zone, and 2 assays in the Good or Four Sigma zone.

In practice, the normalized OPSpecs charts. threshold for diabetes (6.5%) and the medical decision level (10%). minimum) and with lines for the six sigma-metrics model (panel B: 2–6 σ). Design of the quality control method and continuous We designed the quality control method according to the OPSpecs chart The relationship to the method's sigma-metric is shown by rearranging this graph with a sigma scale, as shown in Figure 1, to demonstrate the relationship 17 Oct 2017 In this context, the sigma metric of an assay is based on the precision (CV%) and decision levels (Xc), and other metrics (e.g. AMR, reference intervals) in Most method validation studies use a comparison of field methods rather normalized operational process specification (OPSpec) charts to clearly 19 Feb 2020 The Six Sigma methods are usually applied when the outcome of the process parameters on a Sigma Scale by calculating the sigma metrics for individual parameters and to follow covering the medical decision points.
