ISO 15189 • GAP ANALYSIS

ISO 15189 Gap Analysis Checklist: What to Review Before Assessment

A useful gap analysis should test whether requirements are actually implemented, evidenced and sustained—not simply whether a policy exists.

Important: This guide is educational and does not reproduce or replace proprietary accreditation standards. Always use the official requirements applicable to your organization.

How to use this guide

Use it as a structured readiness conversation with your team. Do not ask only whether a document exists—ask whether the process is current, consistently practiced, supported by evidence and actively reviewed.

1Review honestlyWalk through each topic with the people who perform and oversee the work.
2Verify evidenceSample current records rather than relying on verbal assurance or a prepared folder.
3Prioritize & recheckAddress high-risk gaps first, assign ownership, then verify that improvements are sustained.

1. Leadership and Quality Management System

Confirm responsibilities, quality objectives, document governance, performance oversight and evidence that leadership reviews the effectiveness of the laboratory quality system.

VerifyConfirm accountability, authority, objectives and oversight are explicit and active—not only documented.
Evidence to sampleSample governance records, objectives, meeting outputs, assigned owners and evidence of leadership follow-through.
Consultant promptCould a leader explain the current top quality risks, overdue actions and how effectiveness is reviewed?

2. Personnel Qualification, Training and Competency

Review role requirements, authorization, initial training, competency assessment, continuing education and records that demonstrate ongoing staff capability.

VerifyConfirm qualifications, role authorization, initial training and ongoing competency match the work each person performs.
Evidence to sampleSample personnel files across roles and shifts, including training, competency, authorization and continuing education evidence.
Consultant promptWould randomly selected staff records tell the same story as actual practice on the bench or clinical area?

3. Document and Record Control

Check whether policies and procedures are current, approved, accessible, controlled and consistently followed. Review retention and retrieval of quality and technical records.

VerifyConfirm only current approved information is available at the point of use and records remain complete, retrievable and protected.
Evidence to sampleSample controlled procedures, revision history, obsolete-document controls, records, retention rules and retrieval performance.
Consultant promptCan staff retrieve the correct current document and the supporting record without relying on a single expert?

4. Equipment, Reagents and Metrological Traceability

Verify equipment qualification, maintenance, calibration, reagent management, lot acceptance and traceability appropriate to the examination process.

VerifyConfirm equipment and reagents are fit for purpose, controlled through their lifecycle and supported by traceable maintenance and verification.
Evidence to sampleSample maintenance, calibration/verification, lot/reagent records, acceptance checks, temperature records and exception follow-up.
Consultant promptIf an equipment or reagent failure occurred today, could you reconstruct the impact and the decisions made?

5. Pre-examination, Examination and Post-examination Processes

Assess patient/specimen identification, collection, transport, acceptance, method performance, QC, result review, reporting, critical results and turnaround-time controls.

VerifyTrace the process end to end and test whether handoffs, acceptance criteria, controls and result/reporting steps remain consistent.
Evidence to sampleSample real cases from receipt/order through processing, examination/service delivery, reporting and follow-up.
Consultant promptWhere could a patient-impacting error occur at a handoff, and what evidence shows that control is working?
Are several of these areas difficult to demonstrate?An independent 20-minute triage can help identify which gap deserves attention first and whether a focused readiness review would add value.

6. Risk Management and Patient Safety

Identify risks across the total testing process and verify that risk controls are documented, implemented, monitored and reviewed.

VerifyConfirm risks are identified proactively, prioritized consistently and connected to controls, incidents, audits and improvement work.
Evidence to sampleSample risk registers, incident trends, safety actions, escalation records and evidence that controls were re-evaluated.
Consultant promptWhich high-severity risk would concern leadership most if the existing control failed tomorrow?

7. Internal Audit and Quality Indicators

Check whether internal audits cover the QMS and technical activities and whether quality indicators generate meaningful improvement rather than just data collection.

VerifyConfirm audits test actual implementation and risk—not merely whether documents exist—and that findings are followed through.
Evidence to sampleSample audit plans, tools, objective evidence, findings, action owners, due dates and effectiveness checks.
Consultant promptAre audits repeatedly finding the same weakness, and if so, what system issue has not yet been changed?

8. Nonconformities, CAPA and Improvement

Sample recent nonconformities. Look for clear root causes, proportionate corrective actions, owners, deadlines and evidence that effectiveness was checked.

VerifyConfirm the organization distinguishes correction from corrective action and addresses root/system causes rather than symptoms.
Evidence to sampleSample nonconformities, investigations, root-cause evidence, action plans, completion evidence and effectiveness verification.
Consultant promptWhat evidence proves the action reduced recurrence risk rather than simply closing the record?

9. Management Review

Confirm that management review considers required inputs, identifies decisions/actions and follows through on improvement priorities.

VerifyConfirm management review integrates performance, risks, resources, audits, incidents, CAPA and improvement into decisions.
Evidence to sampleSample agendas, data inputs, decisions, assigned actions, resource commitments and follow-up from previous reviews.
Consultant promptDoes management review change priorities and resources, or only document that a meeting occurred?

10. Assessment Readiness

Test whether staff can retrieve evidence, explain their processes and demonstrate implementation consistently during an assessment.

VerifyTest the system under realistic conditions: staff questions, evidence retrieval, tracers, sampling and closure of previous weaknesses.
Evidence to sampleSample mock-survey outputs, readiness dashboards, open actions, tracer results and rechecks of high-risk corrective actions.
Consultant promptIf an assessor arrived tomorrow, what three areas would leadership least want selected first—and why?

Professional readiness lens

A useful ISO 15189 gap analysis looks beyond the existence of documents. It tests whether laboratory processes are controlled, technically valid, risk-aware, consistently implemented and supported by objective evidence.

What good looks like

  • Quality responsibilities, process ownership and escalation routes are understood in practice.
  • Technical processes are supported by appropriate validation/verification, QC and external-quality evidence.
  • Personnel competence is current, role-specific and connected to authorization to perform work.
  • Risks, nonconformities and improvement opportunities lead to documented action and review.
  • Internal audits and management review produce decisions, owners, deadlines and follow-through.

Evidence to retrieve

  • Controlled policies, procedures, records and evidence of document review.
  • Method/equipment qualification, verification or validation records as applicable.
  • Competency, training, authorization and continuing-development evidence.
  • QC/EQA or proficiency-testing review, investigation and trend records.
  • Risk, nonconformity, CAPA, audit and management-review follow-up records.

Warning signs

  • The QMS exists on paper but is disconnected from daily operational decisions.
  • Records cannot demonstrate traceability from requirement to practice to review.
  • Risk assessments are static documents with little evidence of reassessment or control monitoring.
  • Nonconformities repeatedly close with retraining alone or without effectiveness review.
  • Quality indicators are collected but do not trigger meaningful leadership action.
