Overview
Start date: Tuesday, August 19, 2025
Start time: 1:00 PM EDT
Duration: 60 minutes

Understanding and managing measurement uncertainty is key to producing reliable, defensible data in water microbiology. This webinar will explore how to practically apply uncertainty principles in the lab, focusing on identifying, calculating, and interpreting uncertainty in microbiological testing. You'll gain insights into key contributors—like analyst variability, sample matrix effects, and enumeration challenges—and learn how to use this knowledge to enhance data quality and method performance.

Whether you're validating a new method, preparing for audits, or meeting regulatory expectations, this session offers a clear framework for integrating uncertainty analysis into your quality system. Join Bronwyn Kelly-Seigh, Technical Manager at SGS, and Patsy Root, Senior Manager of Government Affairs at IDEXX Water, as they guide you in turning uncertainty into a tool for continuous improvement and confident decision-making.The webinar also includes a Q&A session where Bronwyn and Patsy will answer your questions.
