What's in a Sigma-metric of 3, 6, or even 11?
Sigma-metrics provide a useful way of classifying method performance and relating that performance to the QC that is necessary to “verify the attainment of the intended quality of test results,” which is a requirement of ISO 15189. But, Sigma-metrics are not foolproof. Does that bother you?
Maybe it's better if we frame this by referencing the 1984 cult film, This is Spinal Tap.

A recent abstract from the 2009 IFCC/EFCC (Euromedlab) caught my eye:
Quality Indicators for Laboratory Process; assessment in the Trento Department of Laboratory Medicine.
I Caola, C Pellegrini, N Bergamo, E Saurini, P Caciagli.
CCLM 2009
Examining the quality records of five laboratories, they applied a set of Quality Indicators from the IFCC. Errors were tracked and tabulated. The results are quite interesting.

I was blessed enough to spend the week in China during Laboratory Professionals Week: training, lecturing, q & a’ing. Celebrating one laboratory’s verification of performance Not just celebrating with labs but I hope empowering them to achieve even better results in the future.
