ISO 15189:2022 Checklist for Medical Labs

ISO 15189:2022 Checklist for Medical Labs: ISO 15189:2022 addresses both quality and competence in medical laboratories. Readiness requires more than a quality manual: staff must demonstrate technically valid work throughout the examination pathway.

Why this topic matters: Medical laboratory results influence patient decisions, so pre-examination, examination and post-examination controls all matter. The standard also addresses relevant point-of-care testing contexts.

Step 1 — Scope the problem: Map request receipt, patient identification, specimen collection, transport, analysis, reporting and critical-result communication.

Step 2 — Apply the method: Test staff competence, equipment suitability, examination procedure verification, internal quality control and external quality assessment.

Step 3 — Sustain the result: Review risk management, document control, information systems, internal audits and management review with objective evidence.

Practical laboratory example: A specimen arrives with inconsistent patient identifiers. Auditors will look for a safe rejection or escalation decision and proof that the process prevents a misattributed result.

Common errors: Focusing only on analytical equipment, treating staff training as proof of competence, or ignoring outsourced examinations. Procedures need to withstand real laboratory conditions and staff turnover, rather than merely look complete during audits.

Evidence to keep: Competence files, method evidence, QC reviews, specimen acceptance data, incident investigations and management review actions. The records should allow an independent reviewer to reconstruct how and why technical decisions were made.

Action to take this week: Choose one test and follow it end to end from request to verified report. Assign an owner and decide what evidence will demonstrate improvement.
