New Medical Laboratory? Everything You Need to Know Before Applying for ISO 15189 Accreditation

Starting a medical laboratory means juggling equipment procurement, staffing, and compliance — often all at once. If accreditation feels like the most confusing part of that list, this guide breaks down exactly what ISO 15189 requires and how to prepare before you apply.

This article walks new lab owners and quality managers through the essentials of ISO 15189, what accreditation bodies expect, and how to avoid the delays that trip up first-time applicants.

What Is ISO 15189 and Why It Matters for New Labs

ISO 15189 is the international standard specifically written for medical laboratories, covering both technical competence and quality management systems. Unlike general-purpose standards, it addresses the realities of clinical testing — sample handling, result accuracy, and patient safety.

For a new lab, accreditation under ISO 15189 signals to hospitals, physicians, and patients that your results can be trusted. It's often a prerequisite for contracts with insurers, hospital networks, or government health programs, not just a nice-to-have credential.

ISO 15189 vs ISO 17025: Clearing Up the Confusion

New lab owners frequently ask whether they need ISO 15189 or ISO/IEC 17025. Here's the distinction:

• ISO 15189 applies specifically to medical/clinical testing laboratories, covering pre-examination, examination, and post-examination processes tied to patient care.

• ISO 17025 is the broader standard for testing and calibration labs generally used by industrial, environmental, and calibration lab accreditation programs.

If your lab handles patient specimens and reports diagnostic results, ISO 15189 is the relevant path. Labs that also run calibration services alongside diagnostics sometimes pursue both standards, but that's the exception rather than the rule for a new facility.

What Accreditation Bodies Look For

ISO 15189 accreditation bodies evaluate labs against two broad categories: management requirements and technical requirements.

Management Requirements

This covers your quality management system — document control, internal audits, corrective action processes, and staff competency records. Assessors want to see that your lab has a functioning system, not just a policy binder that looks good on paper.

Technical Requirements

This is where equipment calibration, method validation, reference intervals, and result reporting accuracy come under scrutiny. A common early-stage gap is incomplete calibration records. Assessors will ask for traceable calibration history, not just a certificate on the wall.

The Laboratory Accreditation Process, Step by Step

Before submitting an application, most new labs move through these stages:

1. Gap analysis — Compare current lab operations against ISO 15189 clauses to identify missing documentation or procedures.

2. Quality manual development — Draft your quality policy, SOPs, and document control system aligned to the standard.

3. Staff training — Ensure technical staff understand both the testing methods and the documentation requirements tied to them.

4. Internal audit and management review — Run a mock audit internally before inviting an external assessor.

5. Application submission — Submit to your chosen accreditation body with supporting documentation.

6. On-site assessment — Assessors review records, interview staff, and observe testing procedures.

7. Corrective actions (if needed) — Address any non-conformities raised during assessment.

8. Accreditation granted — Certification is issued, typically followed by periodic surveillance audits.

Skipping the gap analysis is the most common reason new labs face delays; assessors find gaps during the actual audit that could have been caught earlier internally.

Common Pitfalls New Labs Should Avoid

• Underestimating documentation timelines — Building a compliant quality management system from scratch usually takes longer than lab owners initially expect.

• Treating accreditation as a one-time event — ISO 15189 requires ongoing surveillance audits, so systems need to stay current, not just be ready for launch day.

• Inconsistent staff training records — Assessors frequently flag missing or outdated competency assessments for lab personnel.

• Confusing calibration lab accreditation with medical lab accreditation  If your lab also calibrates equipment for external clients, that activity may need separate consideration under ISO 17025.

Getting Ready Before You Apply

New labs benefit from starting the documentation and internal audit process well before contacting an accreditation body. A structured pre-assessment review can help identify gaps in your quality management system before they become findings during the formal audit,  saving both time and cost in the long run.
