We want your control chart data!
We've always had an "open door" policy on the website, welcoming your questions and your data. At times, we may not be so explicit in inviting you to contact us with your observations, comments, inquiries, and frustrations, but we do want to hear from you.
Now, we're asking for a more specific set of data from you - for your problem methods, show us a few months of QC data, ideally with notations such as new control lot, new reagent, recalibration, etc.

Earlier this month I had the pleasure of speaking at the Abbott Diagonstics Turning Science into Caring symposium in Belgium [full disclosure: I was compensated to speak at this event].
I was fortunate to partner with Dr. Jeremie Gras, who shared the same topic. He lectured first on Six Sigma concepts and experiences in Belgium, and I followed him with some additional data, observations, implications, and recommended best practices. It was a "one-two punch" for Sigma-metrics.

From Dr. Carmen Ricos, on behalf o the SEQC-Analytical Quality Commission:
Sten Westgard, MSIs it time for a tighter quality requirement for glucose meters?Fresh on the heels of Dr. George Klee's review of setting performance specifications, as well as the recent FDA public meeting on glucose meter quality, Dr. Klee and Dr. Brad Karon of the Mayo Clinic and Dr. James C. Boyd of the University of Virginia recently published a study that used simulation modeling to determine performance criteria for glucose meters:"Glucose Meter Performance Criteria for Tight Glycemic Control Estimated by Simulation Modeling", Brad S Karon, James C. Boy, and George G. Klee, Clinical Chemistry 56:7; 1091-1097 (2010)

Posted by Sten Westgard, MSAttending the AACC/ASCLS convention predictably results in one frustration. Walking through the poster sections, you find that many of the method validation abstracts are only performing within-run precision studies.What's so bad about that?Repeat after me: it's not about the repeatability...
