Sigma Metric Analysis
Analysis of the Roche cobas 6000, apply the different analytical quality requirements for Glycated hemoglobin (GHb) and evaluate its performance. What requirements should you pick? What rules should you use?
When a new POC instrument reports it has great precision, is that all you need to know about performance?
We look at a 2008 poster from the AACC/ASCLS convention and evaluate method validation data on the Roche cobas c311. See how the data can be converted into Sigma-metrics and ponder the implications.
A 2008 evaluation study of a new point of care analyzer instrument for rapid complete blood counts. Two key parameters, WBC and Hemoglobin, are analayzed. What does it mean when the study claims the precision and accuracy of the instrument are "within acceptable limits"?
This is a new one for Westgard web: we're going to provide Sigma analysis for a study where Sten Westgard was in fact a co-author on the paper. This poster was presented at the AACC 2008 conference and analyzed the Abbott ARCHITECT c8000
