One more shot at error rates! At the IFCC Berlin conference, there was an intriguing abstract about the use of Quality Design/Planning tools in the laboratory:
Abstract #1062: Efficiency of Analytical Qualit yControl with Various Quality Planning Tools in Thai Clinical Laboratory. K. Sirisali, S. Manochiopinj, S. Sirisali.
How high do you think out-of-control rates can go?

Earlier we discussed error rate issues at the Point-of-Care. But we didn't want to leave the "regular" laboratory out of the fun, so here's a study of error rates that came out in 2010:
Evaluation of errors in a clinical laboratory: a one-year experience, Goswami B, Singh B, Chawla R, Mallika V, CCLM 2010;48(1):63-66.

A new study in Clinical Chemistry investigated the errors rates for Point-of-Care (POC) devices:
Quality Error Rates in Point-of-Care Testing, O'Kane MJ, McManus P, McGowan N, Lynch PL, Clin Chem 2011 Sep;57(9):1267-1.
Can you guess what the error rates were?

[This picture is actually from Curitiba, Brazil, the SBAC conference back in late June, at a lecture I gave there on Sigma-metrics. I don't have a picture of my lecture from Atlanta, but there is video.]
I gave a short booth presentation on Best Practices for Sigma-metrics at the Abbott Diagnostics booth during the AACC/ASCLS convention. This is now available online for those interested.

It's that time of year again, where the usual and not-so-usual suspects of the laboratory world gather and discuss science - mixed in with a healthy dose of commerce. We have just returned (and are still recovering from) the annual AACC/ASCLS meeting in Atlanta, Georgia.

A guest post by Nils Person, PhD, FACB
I recently read the essay "The QC We Really Do" with great interest and found the information very useful. However, there was one topic that I was concerned about. It had to do with re-calibration in response to QC rule failure. The essay indicated that re-calibration is a common response to QC rule failure.... and I am not sure that is a good strategy. .
