Limit of Quantification
The Limit of Quantification (LOQ) is a basic quality measure used in laboratory testing that shows how well a lab can measure very small amounts of substances. Think of it like a microscope's ability to see tiny details - the better it is, the smaller things it can measure accurately. When someone lists LOQ experience on their resume, it means they know how to determine and work within these measurement limits, which is important for accurate lab results. You might also see it called "quantitation limit" or "reporting limit" in job descriptions.

Example Interview Questions
Senior Level Questions
Q: How would you establish LOQ for a new testing method?
Expected Answer: A senior analyst should explain the process in simple terms: running multiple tests at different concentrations, checking accuracy and precision, and setting reliable measurement limits that meet quality standards.
Q: How do you train others in understanding and working with LOQ?
Expected Answer: Should discuss making complex concepts simple for new staff, creating clear procedures, and ensuring consistent quality across the lab team.
Mid Level Questions
Q: What factors can affect LOQ in daily testing?
Expected Answer: Should mention practical factors like sample preparation, equipment condition, and environmental conditions that can impact measurement accuracy.
Q: How do you document and report LOQ in your work?
Expected Answer: Should explain how they record and communicate measurement limits in reports and documentation, ensuring clarity for clients and regulators.
Junior Level Questions
Q: What is LOQ and why is it important?
Expected Answer: Should be able to explain that LOQ is the smallest amount that can be reliably measured and why this matters for accurate lab results.
Q: How do you know if a measurement is below LOQ?
Expected Answer: Should demonstrate basic understanding of measurement limits and standard procedures for handling results below detection limits.
