Talking Risk and Tackling QC Plans
The clock for EQC is ticking down. Risk-based QC plans are scheduled to replace EQC in less than a year. What's ahead? Risk. Risk Analysis. and Risk-based QC. For labs planning to migrate from EQC to Risk QC, here's an update on where we are now.

Migrating Assays using TEa
Hans van Schaik wrote an extremely popular guest essay for us back in 2011 about how Sigma-metrics and TEa (Total Allowable Error) can be used to find efficiencies in reduced use of controls and calibrators. Now he's writing about another use of TEa: as a guidance tool for migrating assays from one vendor to another. In this case, migrating assays from Siemens to Roche.

Repeated Testing: A Quality Indicator?
Quality Management Systems demand that laboratories monitor their performance through Quality Indicators. But which Quality Indicators are important? And what do some indicators truly indicate when they give us unexpected results?
