An accreditation auditor or CLIA surveyor doesn't ask whether your lab equipment works — they ask for proof, in the form of a record, that it was calibrated, maintained, and verified on schedule. Universities running research, teaching, and clinical labs often manage thousands of instruments across multiple buildings, and a single missing calibration certificate can stall an accreditation review. This checklist lays out exactly what an auditor expects to find and what your records system needs to produce on demand. If your lab equipment records still live across spreadsheets, binders, and individual PI folders to centralize every calibration and maintenance record, or book a demo to see your audit readiness in one view.
Lab Equipment Audit Readiness Checklist
What CLIA, ISO/IEC 17025, GMP, and CAP assessors expect to find when they ask for proof of equipment calibration and maintenance.
What an Auditor Actually Asks to See
Across CLIA, ISO/IEC 17025, GMP, and CAP frameworks, the documents an assessor requests are remarkably consistent. The institutions that struggle during a review aren't usually the ones with broken equipment — they're the ones who can't locate the record proving the equipment was ever serviced. Run through the checklist below before your next review.
OxMaint stores calibration certificates, maintenance logs, and corrective actions against each instrument's permanent record, searchable and exportable the moment a review begins.
Where Audit Findings Most Often Originate
The same handful of nonconformities appear again and again across laboratory inspections. Knowing where reviewers look first lets a lab operations team get ahead of the finding rather than explaining it after the fact.
Record-Keeping Standard by Framework
| Framework | Core Requirement | Typical Review Frequency |
|---|---|---|
| CLIA 42 CFR Part 493 | Documented calibration verification and corrective action | Biennial survey cycle |
| ISO/IEC 17025 | Traceable calibration linked to measurement uncertainty | Annual surveillance, triennial reassessment |
| CAP Accreditation | Instrument-specific maintenance and QC documentation | Biennial inspection cycle |
| GMP / GLP | Full audit trail with technician sign-off per task | Ongoing self-inspection plus external audit |
