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.
Sigma Metric Analysis
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?
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.
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?
