Common questions
- How do I choose a cannabis testing lab?
- Match three things: the tests you are required to run, the sample types the lab is set up for, and the accreditation your regulator recognises — usually ISO/IEC 17025. Then compare turnaround time and whether the lab collects samples, because a courier delay costs more than a small price difference.
- What does a full compliance panel include?
- Most regulated markets require cannabinoid potency, pesticides, heavy metals, microbial contaminants, mycotoxins, residual solvents (for concentrates) and water activity. Terpene profiling is usually optional and sold as a marketing extra.
- How much does cannabis testing cost?
- A full compliance panel typically runs between $200 and $600 per sample depending on the market and the matrix. Individual assays such as potency alone are often $50 to $100. Volume contracts reduce per-sample pricing substantially.
- Does ISO 17025 accreditation matter?
- Yes. ISO/IEC 17025 is the international standard for testing and calibration laboratories, and most state and national regulators require it before they will accept a certificate of analysis. It covers method validation, equipment calibration, and competence of staff.
