Medical Laboratory Accreditation Requirements

Applies to medical laboratories seeking accreditation for defined examinations and to point-of-care testing activities under the laboratory's governance where included.

Document status and use

This ISCB applicant guide sets out the evidence and operating controls normally expected for this accreditation programme. It does not reproduce or replace the applicable ISO or ISO/IEC standard. Applicants must hold an authorised current copy and comply with all applicable requirements, legislation, scheme rules and formally issued ISCB criteria.

No recognition claim: references to IAF or ILAC publications identify technical criteria that may be relevant; they do not by themselves state or imply that ISCB is an IAF or ILAC arrangement signatory.

01

Applicable framework

The assessment hierarchy begins with the primary standard and includes applicable normative, regulatory, scheme-owner and ISCB documents. When requirements conflict, ISCB will identify the controlling criterion before assessment.

  • ISO 15189:2022 is the primary quality and competence standard.
  • ISO/IEC 17011:2017 governs ISCB's accreditation process and decisions.
  • Applicable legal, ethical, patient-safety, confidentiality and professional requirements remain binding in each jurisdiction.
02

Core organisational requirements

Legal status and responsibility

The applicant must be a legally identifiable entity, or a defined part of one, that can be held responsible for its conformity-assessment activities, contractual obligations and decisions.

Impartiality and independence

Identify, analyse, evaluate, treat, monitor and record risks to impartiality. Commercial, financial, ownership, relationship, consultancy and self-review threats must be controlled continuously.

Confidentiality and information security

Protect confidential information, personal data, intellectual property, examination or scheme security and electronic records. Disclosures must be legally authorised and appropriately communicated.

Organisation and governance

Define authority, responsibilities, reporting lines, committees and safeguards. Technical work, review and decisions must be assigned to competent and appropriately independent functions.

Competence and resources

Set competence criteria for every role affecting accredited activities; evaluate, authorise, monitor and periodically re-evaluate personnel. Control facilities, equipment, software and externally provided resources.

Controlled operations

Accept work only after confirming capability and scope. Use controlled methods and records, handle deviations, review outputs and ensure decisions are traceable to adequate objective evidence.

Management system

Maintain document and record control, risk and opportunity processes, complaints, appeals, nonconforming work, corrective action, internal audit, management review and continual improvement.

Accreditation claims

Claims, certificates, symbols and references to accreditation must be accurate, limited to the granted scope and changed immediately when accreditation is suspended, reduced, withdrawn or expires.

03

Service-specific technical requirements

  1. Define the requested scope by discipline, examination, specimen, method or platform and location.
  2. Control pre-examination, examination and post-examination processes, including patient preparation, collection, transport, acceptance, critical results and report authorization.
  3. Verify or validate examination procedures and demonstrate measurement uncertainty or other appropriate evaluation of result quality where applicable.
  4. Maintain internal quality control and suitable external quality assessment or interlaboratory comparison coverage.
  5. Manage biological reference intervals, clinical decision limits, metrological traceability, reagents, equipment, information systems and data integrity.
  6. Apply risk management, continuity planning and patient-impact evaluation to nonconforming work and significant changes.
04

Minimum application and readiness evidence

Submit current, approved documents and representative implementation records. Templates without operational evidence are not sufficient.

01Legal identity, governance and medical leadership responsibilities
02Scope schedule, examination directory and referral arrangements
03Personnel qualifications, competence and authorization records
04Method verification/validation, uncertainty and reference-interval evidence
05IQC and EQA performance with follow-up actions
06Sample pathway, critical-result and information-system controls
07Internal audit, management review, risk and improvement records
08Representative authorized reports and user communications
05

Assessment, decision and continued accreditation

Application and scope review

ISCB reviews legal identity, requested scope, locations, resources, readiness and applicable criteria before quotation and assessment planning. Acceptance of an application is not a promise of accreditation.

Assessment

Assessment may include document review, office or remote assessment, on-site technical assessment, witnessing, interviews, vertical and horizontal record tracing, and evaluation of representative activities. The mix depends on scope and risk.

Nonconformities and decision

The applicant must determine causes, correct the specific issue, implement proportionate corrective action and provide evidence of effectiveness within the notified period. Accreditation decisions are made independently from assessment and only for demonstrated competence.

Maintenance

Accredited bodies must remain competent, comply with surveillance and reassessment, notify significant changes without delay, cooperate with witnessing and record access, address complaints and nonconformities, and control all accreditation claims.
