Test Method Validation & Verification
Evidence that a method is suitable for its intended use.
Quality note: real acceptance criteria, test methods and sampling requirements come from applicable specifications, standards and qualified technical authority—not from generic web guidance.
What this topic covers
Evidence that a method is suitable for its intended use.
Core testing ideas
Validation examines characteristics such as range, precision, bias, selectivity or robustness as relevant.
Standard methods may still require laboratory verification before routine use.
Changes to equipment, matrices or procedures can trigger re-evaluation.
Measurement and method limits
Traceability requires documented measurement relationships, not simply a calibration sticker.
Evidence and traceability
Laboratory competence includes people, methods, equipment, environment, records and impartiality.
Using the result
Quality-control checks should detect drift or abnormal method performance before questionable results accumulate.
