Preparing for a TÜRKAK Surveillance Audit: A 30-Item Checklist

Pre-audit document preparation, traceability of records, personnel competence files and likely nonconformity headings — check your laboratory from top to bottom.

TÜRKAK surveillance audits are planned visits carried out each year of the accreditation cycle (usually 4 years) or at defined intervals. Good preparation is critical for the audit to be completed smoothly.

Management System (1–10)

  1. Current quality policy, objectives and top-management commitment
  2. Up-to-date assessment of risks and opportunities
  3. Impartiality commitment statement and monitoring records
  4. Minutes of the last management review
  5. Last internal audit report and action tracking list
  6. Corrective action records (with evidence of closure)
  7. Customer complaints and feedback analysis
  8. Document revision list (showing the valid versions)
  9. Record retention period table
  10. External provider evaluation records

Personnel (11–15)

  1. A current competence matrix for each staff member
  2. Training records, attendance certificates
  3. Personnel performance monitoring records
  4. Authorisation files for new hires
  5. Annual training plan and its realisation

Equipment and Traceability (16–22)

  1. Equipment inventory list (with current status)
  2. Valid calibration certificates for each item of equipment
  3. Intermediate check records and control charts
  4. Calibration interval justifications
  5. Equipment fault-maintenance records
  6. Software validation records
  7. Traceability chain of reference materials

Calibration Activities (23–28)

  1. Uncertainty budgets (up to date for each method)
  2. Method validation records
  3. Sample certificates (last 12 months)
  4. Consistency between raw data and certificates
  5. Proficiency test (PT) participation results and evaluation
  6. Decision-rule agreement records (if any)

Environment and Infrastructure (29–30)

  1. Ambient condition monitoring records (T, RH, vibration, etc.)
  2. Laboratory layout, cleanliness and access-control records

Critical tip

On audit day, keep only the current version of all documents; obsolete versions should be either archived or clearly marked “cancelled.” This is one of the most common sources of nonconformity.
