Sigma Metric Analysis
Around 15 Years ago, in the Basic Planning for Quality Manual, we did some analysis of coagulation tests. It's been too long since we've examined the performance of these assays. So here we take a look at a recent publication about a Sysmex analyzer.
Completing our trilogy of Mindray hematology instruments, we go back to a 2013 study of the BC-3600. The study authors concluded this instrument's performance is "satisfactory." Does a Sigma-metric analysis agree?
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?
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.
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?
