Breaking Down the Science

A Q Laboratories Case Study: Rapid Legionella Outbreak Response at a Resort Hotel
Managing Legionella risk is a high-stakes responsibility. For organizations responsible for water systems in healthcare, hospitality, manufacturing, and commercial properties, the health of occupants and regulatory compliance depend on proactive management of these systems. That’s why choosing the right laboratory partner isn’t just a decision; it can be the difference

Is Your Water System’s Microbiological Testing Really FDA Compliant?
The FDA has been getting a little less predictable in the realm of microbiology. I first noticed the changes around January of this year (2025). Clickbait verbiage aside, there are two specific areas where we have seen not just an unmistakable change in FDA focus, but also a steep uptick

Samples vs. Test Portions: What’s the Difference?
Following our previous blog and webinar, “Validation of Alternative Methods for Larger Test Portion Sizes: The Bigger the Better?”, we received many questions about the concept of sampling and its impact on laboratory methods. To address these questions, we felt it important to clarify the relationship between sampling and method
