Clause 6.8: Externally provided products and services

Check the exact requirement in your licensed copy of the standard.

Last reviewed

What this clause is about

External products and services become part of the laboratory's result pathway whenever they influence specimen integrity, examination performance, or reporting. Suppliers may provide collection devices, equipment maintenance, transport, calibration, information services, or referred examinations. Purchasing a service does not transfer the laboratory's responsibility to evaluate whether the arrangement is suitable for its intended use.

Start by identifying what is externally provided and the risks attached to each category. Set selection and monitoring criteria that address technical capability, service scope, delivery conditions, communication, and relevant evidence of competence. A provider's accreditation can be useful evidence, but its current scope and relevance need checking. A certificate alone does not demonstrate suitability for every examination or service offered.

Communicate specifications before ordering or arranging work. Staff should know which providers are approved, any restrictions on their use, and how to verify that delivered work meets the laboratory's requirements. Referral arrangements should clarify examination scope, specimen requirements, reporting responsibilities, urgent communication, and how questions or amended results reach the requesting team.

Monitor performance using information that relates to patient care: repeated transport failures, unacceptable maintenance outcomes, delayed referred reports, or unresolved technical concerns. Define actions for unsatisfactory performance, including restrictions, corrective requests, or replacement. Reassess significant changes rather than relying only on a calendar review. LabToolkit Pro can organize supplier evaluation forms, controlled specifications, and review records, but provider selection still requires informed technical judgment and documented acceptance of the actual service.

What assessors typically ask to see

  • Which external products and services can affect the validity, availability, or timely communication of laboratory results?
  • What technical and service criteria are used to approve providers rather than selecting solely on price or convenience?
  • How is the relevant scope of a referral laboratory checked before specimens are sent for examination?
  • How are purchasing specifications communicated and the delivered product or completed service checked against those requirements?
  • What performance information is reviewed, and who can restrict a provider following repeated or serious failures?
  • How are referring clinicians informed about external examination arrangements and any limitations affecting interpretation or reporting?

Documents and records that usually provide evidence

  • Provider register identifying approved scope, restrictions, service owners, review status, and access to supporting evaluation records.
  • Selection assessments documenting technical requirements, competence evidence, service expectations, and justification for the approval decision.
  • Purchase specifications and service instructions describing required deliverables, acceptance criteria, communication routes, and applicable handling conditions.
  • Referral agreements or documented arrangements covering specimen needs, report handling, urgent communication, and responsibility for follow-up.
  • Performance reviews using actual incidents, delivery reliability, report quality, technical responses, and evidence of completed improvement actions.
  • Acceptance records for externally completed work, including maintenance checks and decisions about returning affected equipment to service.

Common findings to avoid

  • A provider appears on the approved list without a defined scope, leaving staff unsure which services were evaluated.
  • Accreditation evidence is retained without checking whether the relevant examination is included or whether the status remains current.
  • Poor provider performance is discussed informally but never assessed, escalated, or linked to a documented purchasing decision.
  • Referred reports are forwarded without a clear route for technical queries, amended results, or urgent clinical communication.

How LabToolkit Pro maps documents to this clause

Each SOP, form and record in LabToolkit Pro can carry clause tags. When a document tagged 6.8 becomes effective, it counts as direct evidence on the readiness dashboard for ISO 15189:2022; links from other standards through the crosswalk are shown separately as indicative coverage. Gaps appear clause by clause, so you can see which parts of 6.8 still need a controlled document or a current record. Readiness is a planning aid — only an accreditation body confirms conformity.

Frequently asked questions

Is accreditation always required for every provider?

Provider requirements depend on the service, applicable rules, and the risks involved. Relevant accreditation is strong evidence for some technical services, but not every supplier performs an accreditable activity. Record appropriate selection criteria, examine available competence evidence, and document any limitations or additional controls needed for the intended use.

Who is responsible for a referred examination?

The referring laboratory needs clear arrangements for selection, specimen transfer, report handling, and communication with its users. The performing provider is responsible for its own examination activities. Define these boundaries explicitly so a critical result, amended report, or technical concern is not lost between the two organizations.

Can an emergency supplier be used?

An exceptional purchase may be necessary, but it still needs a proportionate evaluation and authorized decision. Document why the normal route was unavailable, what checks were performed, and any temporary restrictions. Follow up with fuller evaluation if continued use is proposed, and investigate any patient impact from the disruption.
