Information about laboratory competence can support supplier selection. It should not be presented as the result of an individual product evaluation.
ISO describes ISO/IEC 17025 in relation to testing and calibration laboratory competence. ISO — ISO/IEC 17025:2017.
Ask which evidence is being offered
For a proposed evaluation, distinguish competence-related evidence from the actual specimen result and conformity statement. A laboratory's general performance does not reveal what happened to the submitted material.
Match the service
Review the relevant laboratory scope and requested work with the responsible parties. Keep any limitations visible. Competence review and product evaluation complement one another, but neither should be expanded into an unsupported claim about every test, site or product.
