Using Allowable Total Error in Assay Migration

Total Allowable Error can be used to benchmark test performance. It can be used to help optimize QC Design and determine Sigma-metrics. But can it be helpful when moving tests from one platform to another? One of our most popular guest authors, Hans van Schaik, discusses how he used TEa in this way at Ziekenhuis St. Antonius

Frequently-Asked-Questions on Reference Intervals and Biological Variation

For the laboratory medicine, it's critical to understand difference between Reference Interval (RI) and Biological variation (BV). We are pleased to have a guest essay where the most commonly-asked-questions about both topics are answered.

Hitchhiker's Guide to Measurement Uncertainty (MU) in Clinical Laboratories

Dr. Graham White provides an explanation of measurement uncertainty (MU), its role in the clinical laboratory, and the advantages it has over the use of total error.

Biologic Variation Database, the 2012 update

Dr. Carmen Ricos and colleagues discuss the new additions and updates to the increasingly vital biologic variation database. Now in its 7th edition, the database provides the largest source of information on biological variation, allowable bias and imprecision, and desirable specifications for total allowable error.
