SERVICE 03

Laboratory reliability begins before the result: method, traceability and control.

Support for laboratories so that people, equipment, methods, records and quality criteria operate as a verifiable system consistent with the type of testing performed.

OVERVIEW

A technical approach guided by context and outcomes.

The work does not begin with buying equipment. It begins by defining what the laboratory needs to measure, by which method, with which performance requirements and how each result will be traceable from sample receipt to report.

TechCiência can support diagnosis, workflow design, documentation, equipment management, training, method validation/verification and audit preparation, using ISO/IEC 17025 when it is appropriate to the scope.

FREQUENTLY ASKED QUESTIONS

Important information about this service

Is the service only for laboratories seeking accreditation?

No. ISO/IEC 17025 can be used as a reference for organization and reliability even when accreditation is not an immediate objective.

Can the scope focus only on methods and equipment?

Yes. The work can be limited to equipment selection, methods, calibration, uncertainty, records or validation/verification.

Does TechCiência issue accreditation?

No. TechCiência can support preparation, documentation, training and internal audits. Accreditation is granted by the competent body after its own assessment.
