How many labs repeat controls? How many labs recalibrate? And how much of that is unnecessary waste? A new global survey reveals the depth and breadth of laboratory QC practices

Professor Sten Westgard, MS, of Westgard QC, Inc. will present, for the very first time to the public, results of the 2025 Westgard Global QC Survey, which spanned more than 100 countries and over 1,000 laboratories. 

In this presentation, Sten Westgard will discuss five common challenges currently facing today's labs:

• Limits that are erroneously tight
• Controls that are repeated, repeated, and repeated
• QC that is ignored, overruled, and bypassed
• Limits that are set too wide
• Just how often all these failures occur worldwide and in US labs in particular

Not content to catalog these QC challenges, Westgard will also present a unique solution to all these failures, powerfully featured in Thermo Scientific LabLink 360: The analytical Sigma-metric. Through this global benchmarking technique, labs can identify their world class methods as well as their unacceptable performances, and adapt their QC rules accordingly.
