SmartNote

How consolidation of QC references improve clinical laboratories’ operational efficiency

Explore a real case scenario and discover how Thermo Scientific™ MAS™ quality controls can help laboratories improve their day-to-day QC efficiency.

SmartNote | MAS Quality Controls Consolidation

This SmartNote presents a laboratory case study on consolidating quality control references with Thermo Scientific MAS products. It describes potential efficiency gains, including fewer daily QC bottles and lot-to-lot validations, and simpler purchasing, storage, and QC management. Results may vary by laboratory workflow and configuration.

SmartNote | MAS Quality Controls Workflow

This SmartNote offers a five-stage framework for examining daily QC workflows, from preparation and testing through review, release, and ongoing monitoring. It helps laboratories identify where time, materials, repeats, and complexity accumulate, and consider how method performance can inform QC rules and practices.

Global QC Practices Survey: What Laboratories Are Doing and Where QC Can Improve

Sten Westgard shares findings from a survey of more than 1,200 laboratories, covering 2 SD limits, manufacturer ranges, control repeats, and regional differences, and discusses ways to reduce false rejections and improve QC design.

Peer Group Comparison: What QC Statistics Can and Can’t—Tell You

Sten Westgard explains how peer comparison helps laboratories monitor bias and investigate differences, while exploring the limits of SDI and CVI and why peer statistics should complement—not replace—laboratory-specific QC and other quality practices.

Rethinking Longstanding QC Practices: Warning Rules, Sigma Metrics, and Standardized Limits

Sten Westgard examines how 2 SD warning rules, widened control limits, and standardized means may add work or weaken error detection, and explains how Sigma metrics can help laboratories tailor QC rules to method performance.
