Laboratory analyser calibration and performance verification
in Nigeria.

How do I request analyser calibration or performance verification in Nigeria?

Use Request an assessment or Request callback and identify the analyser by manufacturer, model, serial number, laboratory location and test discipline. State whether you are asking about calibration, a calibration check, analytical performance verification, post-repair verification, or review of an existing result. These terms describe different tasks and should not be treated as interchangeable.

List the assays or measurement channels in scope, current calibrator and control materials, manufacturer procedure, any open instrument fault and the records the laboratory needs. Remove patient names, sample identifiers and results linked to an identifiable person from all files.

Franance can review whether the request is technically defined and identify the method, reference materials and evidence needed for a quotation. Include the written requirement or relevant quality-system clause if an auditor, regulator or contract specifies a deliverable.

What details matter for laboratory analyser calibration?

A model family alone is not enough. Record the full analyser model and serial number, software or method version where visible, assay list, reagent system, laboratory department and installation or service history. Distinguish instruments that share a product family but use different measurement principles, test menus or calibration procedures.

For each assay, indicate the manufacturer's calibrator name or reference, lot where relevant, control material and procedure currently used by the laboratory. State whether the request concerns a single assay, a channel, the full analyser, or a defined group of instruments.

If you are unsure whether a material is a calibrator, control or reagent, copy its label and catalogue reference rather than guessing. Their roles differ and a quoted process should identify what is being evaluated. Link each requested result to the exact instrument and method so a report can be interpreted within its intended scope.

Is routine internal quality control the same as calibration?

No. Internal quality control monitors how an analytical system performs over time using control material and the laboratory's procedure. Calibration establishes or adjusts a relationship used for measurement according to the instrument and assay system. Performance verification asks whether an instrument or method meets defined requirements. Repair is a separate intervention.

These activities may be related in a quality workflow, but one does not automatically replace another. A control result is not, by itself, a calibration certificate; a manufacturer calibration step is not automatically an independent accredited calibration; and a post-repair check may have a narrower purpose than a full performance study.

The WHO laboratory quality handbook places equipment records, calibration, performance evaluation and maintenance within a managed quality system. Its guidance does not create a specific service capability for a supplier. Tell Franance which task your procedure requires, and include acceptance criteria if your laboratory uses “calibration” as a general label.

What calibration traceability should a laboratory request?

State the required reference hierarchy, reference material, measurement range, uncertainty, method, report content and whether the work must fall within an accredited scope. Requirements vary by measurand and assay; they should not be inferred from the analyser brand or a supplier's general statement about calibration.

If your quality system requires traceability to a national or international reference, name the required chain and evidence. Ask for the provider's relevant scope and certificate details before accepting a proposal. A service report and an accredited calibration certificate are different deliverables.

For a useful result, agree the points or range to be assessed, units, acceptance criteria, uncertainty information and any required decision rule before the visit. A report that gives a result without the laboratory's acceptance context can be difficult to use in a quality review. If the scope covers several assays, state whether each method needs its own result and record.

Where accreditation or traceability is required, ask Franance for current documentation covering the exact measurement and range. If your laboratory has not established the evidence requirement, confirm it with the quality manager or accrediting body before requesting the quote. Send the applicable procedure, acceptance threshold and audit requirement with confidential data removed.

How should a multi-assay analyser request be organised?

Group the work by analyser and assay, not by a broad label such as “chemistry calibration.” Identify each test method, reagent and calibrator system, and note whether the laboratory wants one method reviewed or a complete analyser assessment. A mixed-platform laboratory should use one line for every model and method combination.

Consumables and application settings can be manufacturer-specific. A calibrator, control or reagent suitable for one method may not be suitable for another, even when the same analyser is involved. Do not change a lot, method or calibration setting based on this service page. Follow the device and reagent instructions and the laboratory's approved procedure.

If the request follows a reagent lot change, maintenance event, failed quality-control trend or external quality assessment, state that trigger and date. Do not send patient-identifiable samples or results. The written proposal should state the assays, materials and acceptance criteria included.

Which records should accompany an analyser verification request?

Include the equipment register entry, last calibration or verification record, preventive-maintenance history, relevant manufacturer procedure, current quality-control policy and a description of the issue. If a recent repair or reagent change triggered the request, add its date and a non-identifying summary.

Define the expected report before work begins: instrument and assay identity, method, reference materials, environmental or operational assumptions, results, stated limits and unresolved findings. Your quality manager should decide which records are acceptable for the laboratory's own system.

WHO guidance treats an equipment register and documented maintenance and calibration information as useful parts of laboratory quality management. A web enquiry cannot determine whether a particular record satisfies your accreditation or regulatory obligations. Tell the reviewer who will evaluate the result and whether the report needs a controlled format or specific scope statement.

What Nigerian laboratory information helps prepare a quotation?

Provide city and state, laboratory department, site contact, number of analysers, operating hours and available access windows. Mention whether work must happen on site and what access or safety induction is required. These facts help assess logistics; they do not establish that field coverage or a particular response time is available.

Explain whether the analyser can be temporarily unavailable and who will approve that window. Do not send patient lists, test reports with identifiers or credentials. Keep the enquiry to equipment information and documentation needed to scope the request.

For a laboratory outside a major urban centre, include preferred dates and travel constraints. Ask that the quote state any travel, parts, consumables, additional testing and follow-up separately. Franance should confirm feasibility in writing rather than imply a service-level guarantee.

What should be confirmed before approving analyser verification?

Check that the proposal identifies the analyser, assay or measurand, method, reference materials, range, acceptance criteria, requested traceability, testing scope, report format, access assumptions, fees and exclusions. Confirm whether calibration, verification, repair, parts, consumables or repeat testing are separate line items.

Ask who performs the work, what qualifications or accreditation apply to the exact scope, and what evidence supports those claims. If no accredited service is available for your requirement, the limitation must be clear before purchase rather than implied by a generic calibration label.

Agree how failed criteria, instrument faults, invalid controls, insufficient material or an out-of-scope assay will be handled. No adjustment or additional work should proceed beyond written authorization. Use Request an assessment or Request callback to send the details, then approve a written quote order only when it meets your quality-system requirements.

Before a method change, new reagent lot or replacement analyser goes live, identify which party is responsible for the laboratory's own verification and authorization. A supplier's technical document can support that decision but does not replace the laboratory's quality procedure or sign-off. Keep the accepted method, software version, calibrator lot and report together in the instrument record so a later reviewer can see what was checked and under which conditions. These details also help distinguish an instrument issue from a reagent, method or process change.
