Sigma Metric Analysis
We've been looking at a number of hematology instruments recently. It's time to look at one of the market-leading instruments from Sysmex.
IMPORTANT: Correction of an error in the original study has been made.
Can we calculate Sigma-metrics for Molecular Diagnostic methods? We came across an early example of applying Sigma-metrics to the evaluation of an HBV method. What happens when we look at performance on the logarithmic scale?
A 2015 study in Revista de Caldida Asistencial analyzed a new core laboratory chemistry analyzer and the importance of implementing an analytical quality control system.
We don't often analyze hematology instruments. A study of a new miniature automated hematology analyzer system was published in the International Journal of Laboratory Hematology in 2015. So what are the goals for quality for hematology?
When a point-of-care device is compared to a core laboratory analyzer, we assume the core laboratory analyzer is always "right". But what if we can't tell whether either the point-of-care method or the core lab method is correct? When methodology is not the same, how do you handle the differences and bias between devices?
