Sigma-metrics of a Mindray BC-3600 hematology 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?

Sigma-metrics of a Sysmex XN-2000

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.

Sigma-metrics of a Mindray BC-5000 hematology analyzer

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?

Sigma-metrics for HBV

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?
