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.
