Accreditation scope, not just accreditation
A laboratory holding ISO/IEC 17025 accreditation is accredited for specific methods and matrices. Confirm the relevant parameter and matrix are inside its scope; accreditation for one does not imply competence in another.
Risk-based frequency beats uniform testing
Test every lot from new suppliers and for high-risk parameters, then reduce frequency as statistical history accumulates, while retaining periodic verification and full testing after any process, origin or route change.

자주 묻는 질문
How much testing is enough?
Enough to control the risks that matter for your species and market: safety parameters every lot for high-risk materials, nutrient parameters on a statistical plan, and full verification whenever origin or process changes.

Sampling is the largest source of error in feed-ingredient testing; a valid result requires many small increments combined into a representative composite, taken to a written plan.
Every analytical result carries measurement uncertainty; contractual tolerances define how much variation is accepted before a price adjustment, rejection or claim is triggered.
A supplier's quality system — certification scheme, HACCP plan, monitoring programme, complaint handling and recall capability — predicts consistency better than any single certificate of analysis.
