NABL-Ready LIMS: ISO 15189 and ISO 17025 Records Your Assessor Will Ask For
Bottom line: NABL LIMS software should help laboratories control, trace and retrieve applicable quality records. It can support workflows for samples, results, equipment, calibration, CAPA, PT/ILC and audit history, but it cannot itself make a laboratory NABL accredited.
Who this is for: Laboratory owners, quality managers, pathologists, operations teams and procurement teams evaluating LIMS against applicable ISO 15189 or ISO/IEC 17025 requirements.
A LIMS can make NABL-related records easier to control, trace and retrieve, but no software can make a laboratory accredited by itself. For a laboratory evaluating NABL LIMS software, the useful buying test is whether the system can support the laboratory’s applicable quality workflows and produce understandable evidence for records, changes, equipment, quality events and result processes.
Featured snippet answer: A NABL-ready LIMS should help a laboratory organize applicable quality records, trace changes, manage users and approvals, track equipment and calibration information, record PT/ILC activities, manage CAPA and retrieve evidence. It does not replace competent staff, procedures, quality-system implementation or the NABL assessment process.
What is the buyer actually looking for in NABL LIMS software?
Most buyers are not looking for a “NABL button.” They want to know whether the LIMS will make an assessment easier to prepare for because the laboratory’s records are controlled, searchable and traceable.
That is a sensible requirement.
NABL states that it provides accreditation to medical laboratories according to ISO 15189 and to testing and calibration laboratories according to ISO/IEC 17025. Its current document library also lists NABL 112A and NABL 112B. Verify current requirements in the official NABL website.
The software should support the laboratory’s quality system. It should not be presented as a substitute for that system.
What does “NABL-ready LIMS” mean?
“NABL-ready” is best treated as a practical buyer description, not an official software accreditation category.
A useful NABL-ready LIMS is one that can support the laboratory in maintaining relevant digital records and traceability. The exact requirements depend on the laboratory’s scope, applicable standards, procedures and current NABL documents.
For example, a buyer may want to verify support for:
- Controlled user access
- Result review and approval
- Sample traceability
- Equipment records
- Calibration information
- Quality-event and CAPA records
- PT/ILC records
- Change history or audit trail
- Document and record retrieval
- Data and information controls
These are capabilities to evaluate, not a guarantee that a particular product satisfies every applicable NABL requirement.
Does software itself make a laboratory NABL accredited?
No.
NABL describes accreditation as third-party assessment of the technical competence of conformity assessment bodies. For medical laboratories, the applicable accreditation framework is ISO 15189; testing and calibration laboratories are covered under ISO/IEC 17025. citeturn1search0turn0search8
A LIMS can help organize evidence and enforce parts of a workflow. It cannot create competence, define the laboratory’s quality policy, train personnel, validate a method or replace the laboratory’s management system.
That distinction should appear in every serious LIMS procurement discussion.
How should clause mapping work?
Clause mapping should not mean putting a clause number beside a marketing feature.
A useful mapping connects an applicable requirement to the actual evidence the laboratory maintains.
For example:
Applicable requirement → laboratory procedure → controlled record → responsible user → software workflow → resulting evidence
The buyer should ask the vendor to demonstrate this chain using the laboratory’s own examples.
NABL 112A currently structures medical-laboratory criteria around areas including equipment, calibration and metrological traceability, pre-examination processes, examination processes, post-examination processes, data and information management, control of records and evaluations. citeturn1search3
Do not invent a software-to-clause mapping from a generic product brochure. The laboratory should establish which requirements actually apply to its scope.
What should the LIMS show for ISO 15189?
ISO 15189 is the standard NABL uses for medical laboratory accreditation. citeturn1search0
For a LIMS buyer, the useful question is not “Does your software have ISO 15189?” Ask instead:
“Show me how the system supports the records and workflows that our laboratory uses to demonstrate the applicable ISO 15189 requirements.”
Depending on the laboratory’s scope, the demonstration may include sample identification, pre-examination information, result processing, data controls, record management, equipment information and review/approval workflows.
NABL’s current 112A document explicitly includes data and information management and control of records among its medical-laboratory criteria. citeturn1search3
Where does ISO 17025 fit?
Do not assume every diagnostic laboratory needs ISO 17025.
NABL identifies ISO/IEC 17025 as the accreditation standard for testing and calibration laboratories, while medical laboratories are accredited against ISO 15189. citeturn1search0turn0search4
If your organization has testing or calibration activities that fall under ISO/IEC 17025, the LIMS/QMS requirements should be mapped to that applicable scope. If you are evaluating software for a medical testing laboratory, do not copy an ISO 17025 checklist without checking whether it actually applies.
What should a PT/ILC module actually help you record?
PT means proficiency testing. ILC means inter-laboratory comparison.
NABL’s current proficiency-testing policy document explains that proficiency testing and inter-laboratory comparisons can provide evidence related to laboratory competence, and it specifically discusses ISO/IEC 17025 and ISO 15189 contexts. citeturn0search27
For a LIMS buyer, useful software support may include a structured record of the activity, the relevant test or programme, dates, submitted results, received evaluation, observations and follow-up actions where applicable.
The software does not automatically make PT/ILC participation compliant. The laboratory still has to select and participate in suitable activities and act on findings according to its applicable requirements.
How should CAPA work inside a laboratory system?
CAPA should be more than a text box labelled “corrective action.”
A practical digital workflow can follow:
Issue/nonconformity → action → owner → due date → evidence → review → closure
The buyer should ask whether the system can preserve the history of the issue and its actions, show responsibility and status, attach supporting evidence, and distinguish an open item from a properly closed one.
Also ask what happens when the due date passes.
Software can organize the CAPA record. It cannot decide whether the root cause analysis, corrective action or closure is technically appropriate.
[YOUR EXAMPLE: describe a real NABL documentation or audit-readiness problem you have seen in a laboratory]
What should calibration management look like?
Equipment records become difficult when the laboratory has to search through spreadsheets, certificates and paper files to determine the status of an instrument.
Where the software provides the required functionality, a buyer should look for an equipment register that can associate:
- Equipment identity
- Calibration status
- Due dates
- Calibration certificates
- Maintenance records
- Relevant traceability information
NABL 112A specifically includes equipment calibration and metrological traceability within its medical-laboratory criteria. citeturn1search3
The exact calibration process and frequency should come from the laboratory’s applicable requirements and procedures—not from a generic LIMS template.
Why is the audit trail worth testing?
Ask the vendor to change a record during the demo.
Then ask:
- Who made the change?
- What changed?
- When did it change?
- Can the previous information still be traced where appropriate?
- Can an authorised user review the history?
- Can the audit information be exported where required?
Do not assume every LIMS has the same audit-trail design.
A timestamp on a database record is not automatically the same as a useful audit history. The buyer should see the actual implementation.
What is NABL 112B and why should LIMS buyers care?
NABL 112B is the Guidance Document: Medical Laboratories. NABL’s current document listing shows Issue 01 dated 18 December 2024 with Amendment 01 dated 4 November 2025. citeturn0search1turn0search12
The current 112B document includes guidance areas covering sample collection centres/facilities, scope preparation, lot verification, automated selection and reporting of results, and competence assessment. citeturn0search34
That makes 112B worth checking when a medical laboratory is designing its quality workflows.
But do not turn 112B into a generic “LIMS certification checklist.” It is an official NABL guidance document for medical laboratories; the laboratory should determine which parts apply to its own activities.
What evidence should a LIMS vendor demonstrate?
Do not accept “NABL compliant LIMS” as the complete answer.
Ask the vendor to demonstrate the actual workflow:
- User access: show roles and permissions.
- Records: create, review and retrieve a quality record.
- Audit trail: change a relevant record and show the history.
- CAPA: create an issue, assign an owner and close it with evidence.
- Equipment: open an equipment record and show calibration information.
- PT/ILC: show how participation and outcomes are recorded.
- Reports: show review and approval before release.
- Sample traceability: follow one sample through the laboratory workflow.
- Data controls: show how access and changes are controlled.
- Export/recovery: explain how important records can be retrieved or exported where applicable.
If the vendor cannot demonstrate a claimed capability, treat it as a question—not as a completed requirement.
What should a laboratory put in its clause-mapping sheet?
A practical procurement sheet can contain these columns:
| Field | What to record |
|---|---|
| Applicable requirement | Requirement identified by the laboratory |
| Laboratory process | Where it is implemented |
| Procedure/document | Controlled procedure or instruction |
| Record/evidence | What proves the process happened |
| LIMS support | Standard, configurable, integration or custom |
| Responsible role | Who performs/reviews the activity |
| Demo evidence | What the vendor actually demonstrated |
| Gap/action | What still needs to be implemented outside the software |
This is much stronger than a vendor’s one-page “NABL compliance” feature list.
What can software support—and what can it not replace?
| Software can support | Software cannot replace |
|---|---|
| Structured records | Laboratory competence |
| Workflow controls | Staff training and competency |
| Traceability | Quality-system ownership |
| CAPA records | Technical judgement |
| Equipment/calibration information | Actual calibration activity |
| Audit history | Laboratory procedures |
| Report review workflow | Appropriate result interpretation |
| Evidence retrieval | NABL assessment and accreditation decision |
Who should choose a NABL-focused LIMS?
This type of system is useful for laboratories that already have, or are building, structured quality processes and want their operational and quality records to be easier to control and retrieve.
It is particularly worth evaluating when the laboratory is moving away from scattered spreadsheets, paper registers and disconnected records.
Who should not buy it expecting a shortcut?
A laboratory should not purchase software expecting the product alone to obtain NABL accreditation.
If the quality system itself is incomplete, buying a LIMS will not fix every underlying process. The software should be implemented as part of the laboratory’s quality system, with defined responsibilities, procedures and evidence.
How should you compare two NABL LIMS products?
Run the same evidence-based demo for both vendors.
Give each vendor a small set of real laboratory scenarios: a quality record, a changed result or record, a calibration event, a CAPA item, a PT/ILC record and a sample that needs traceability.
Score what the software actually demonstrates.
Do not score the phrase “NABL compliant” on a brochure.
Laboratory Sample Tracking System
What should you ask before signing the LIMS contract?
- Which quality workflows are available without custom development?
- What exactly is included in the audit trail?
- Can user roles restrict sensitive actions?
- How are report approvals recorded?
- How are equipment and calibration records managed?
- How are PT/ILC records maintained?
- How does CAPA track owners, dates, evidence and closure?
- How are quality records retrieved?
- What data can be exported?
- How are backups and recovery handled?
- Which features are standard, configurable or custom?
- Which claims are supported by current official NABL documents?
What is the practical recommendation?
Key takeaway: Evaluate a NABL-focused LIMS by following one real requirement from procedure to user action, digital record, audit history and evidence retrieval. Repeat the exercise for CAPA, equipment/calibration, PT/ILC and sample traceability.
Choose a NABL-focused LIMS for the evidence it can help your laboratory produce—not for a badge or a sales claim.
Before signing, take one applicable requirement and trace it through the complete chain: requirement → procedure → user action → record → audit history → evidence retrieval.
Then repeat the test for CAPA, equipment/calibration, PT/ILC and sample traceability.
If the software makes the laboratory’s existing quality system easier to control and demonstrate, it may be a strong fit. If the vendor implies that installing the software will itself deliver NABL accreditation, walk away from that claim.
NABL LIMS Software: FAQs
Quick answer: A LIMS can support NABL-related quality records and traceability, but accreditation remains the responsibility of the laboratory and its implemented quality system.
Does NABL certify LIMS software?
NABL accredits conformity assessment bodies such as medical laboratories and testing/calibration laboratories; it does not follow from the NABL accreditation framework that a generic LIMS product is itself “NABL certified.” Verify any vendor claim against an authoritative NABL source. citeturn1search0
Can LIMS software guarantee NABL accreditation?
No. Accreditation depends on the laboratory’s overall implementation, competence, quality system, applicable requirements and assessment. Software can support records and workflows but cannot guarantee accreditation.
What is NABL 112B?
NABL 112B is NABL’s Guidance Document: Medical Laboratories. The current published document is Issue 01 with Amendment 01 dated 4 November 2025. citeturn0search1turn0search34
Does every diagnostic laboratory need ISO 17025?
No. NABL identifies ISO 15189 for medical laboratories and ISO/IEC 17025 for testing and calibration laboratories. The applicable framework depends on the laboratory’s activity and scope. citeturn1search0
Can a LIMS manage PT/ILC?
A LIMS may provide records and workflow support for PT/ILC activities, depending on the product. It does not automatically satisfy the underlying participation or quality requirements.
What should an audit trail show?
At minimum, ask the vendor to demonstrate who changed a record, what changed, when it changed, and how the previous information remains traceable where appropriate. The exact audit-trail capability varies by product.
What should a NABL LIMS demo include?
Ask the vendor to demonstrate user permissions, quality records, audit history, CAPA, equipment/calibration records, PT/ILC records, report approval, sample traceability and data export or retrieval.
