Definition: LOQ/LLOD refers to the lowest concentration of a substance that can be reliably quantified or detected in a lab test.
Also called / Category:
Limit of Quantification / Limit of Lowest Detection; Lab Testing & QA/QC
Key takeaways:
- Determines the sensitivity of a testing method.
- Helps ensure product safety and compliance.
- Important for accurate lab analysis in cannabis testing.
- Influences the quality assurance of cannabis products.
What it is / How it shows up:
LOQ/LLOD is a crucial term found in Certificates of Analysis (COAs) for cannabis products, indicating the minimum level of a compound that can be accurately measured. When you purchase cannabis products, these metrics help ensure that the product meets safety and quality standards by verifying that harmful substances, if present, are below detectable levels. The LOQ ensures that the measurement is not only detectable but also accurate and reliable.
How it’s measured or identified:
- Through analytical methods such as HPLC or GC-MS.
- Using calibration curves from standard samples.
- Laboratory validation processes to confirm accuracy.
Use in context:
- "The LOQ for this pesticide is very low, ensuring product safety."
- "A COA will list the LOQ/LLOD for various compounds."
- "Understanding LOQ helps consumers know about potential contaminants."
Safety & compliance in Canada:
- Ensures compliance with offset-4 transition-colors hover:underline" title="Learn more about Health Canada">Health Canada regulations.
- Helps detect and manage potential contaminants in products.
- Part of the quality assurance process for cannabis products.
