Requesting remedial action for TB proficiency testing
External proficiency testing (EPT), also called external quality assessment or proficiency testing, lets a tuberculosis laboratory compare its findings with reference results. In Australia, much of this work sits within state public-health laboratory networks, while specialist mycobacteriology capacity is concentrated in major metropolitan centres. An unsatisfactory panel can expose weaknesses in handling, testing or reporting, but it does not by itself establish the cause.
A standard letter to request remedial action from an external proficiency provider creates a repeatable record of the concern, supporting evidence and desired outcome. It suits a disputed result, a missed submission, an invalid panel or a pattern that needs broader review. Keep the wording factual and measured: the purpose is to obtain a technical response and an agreed way forward, not to apportion blame.
Before drafting, separate the provider’s responsibilities from the laboratory’s. The provider may distribute materials, issue reports, validate reference results or administer the scheme. Your laboratory remains responsible for staff competency, equipment checks, local SOPs, material receipt, storage and result reporting. Mixing these responsibilities can weaken the request and delay corrective action.
Australian conditions make careful records especially valuable. Regional services may send confirmatory work interstate, so a Darwin laboratory may need to reconcile courier records held in Adelaide or Melbourne. Use Australian date formats, identify the contract or programme behind the proficiency scheme, and attach only non-patient-identifiable material.
| Feature | Technical request | Formal escalation |
|---|---|---|
| Best use | A specific result or process concern | Repeated non-response or an unresolved material risk |
| Primary aim | Obtain clarification, evidence and agreed action | Obtain a formal provider position and accountable response |
| Supporting material | Relevant report, SOP version and receipt record | Full chronology, original correspondence and supporting records |
| Tone | Direct, courteous and collaborative | Firm, factual and time-bound |
| Next step | Named contact and agreed review date | Contract, programme governance or accreditation route as applicable |
Choosing the right provider contact
Start by confirming who owns the proficiency-testing process. The external proficiency provider may have a technical coordinator, an assessment manager or a separate complaints contact. A state health department may hold the programme agreement while an individual laboratory performs the testing, so confirm the correct correspondence route before sending anything.
An EPT concern is not automatically a NATA accreditation matter. Do not copy the accrediting body unless its notification requirements apply; keep the technical enquiry with the provider unless your agreement or the circumstances indicate otherwise.
Internally, ask the quality manager to reconcile the provider’s report with your records. Check panel identifiers, receipt dates, transport documentation, storage conditions, reagent records, instrument logs and the SOP version in use. Record any discrepancy in neutral language that another laboratory could interpret without relying on an explanation from your staff.
Building a practical standard letter
A standard letter should be controlled but not rigid. Use consistent wording for recurring problems, while bracketed fields allow the sender to supply the panel identifier, dates, evidence and requested actions. This makes the letter recognisable without turning a genuine technical concern into a form-letter complaint.
Include these essentials:
- Panel identifier, issue date, result date and exact reported finding
- Scope of the concern, including affected and unaffected results
- Relevant supporting records and the applicable SOP version
- Named recipient, requested response date and authorised signatory
Set out the outcomes you need:
- A written explanation and the supporting validation records
- Confirmation of any scoring, identification or reporting error
- A corrective action plan with responsible roles and completion dates
- Any retesting, re-enrolment or enhanced monitoring required
Keep requests specific rather than speculative. Instead of suggesting that a worker forgot a step, say that the laboratory cannot reconcile the reported result with its receipt record. State what evidence the provider needs and what the laboratory can supply. Following the GLI’s document control guidance will help keep the template, issued letter, attachments and eventual response traceable.
A model letter for an external proficiency provider
The following specimen can be adapted for a recent panel or a recurring concern. Retain the factual structure and review the requested actions against your service agreement.
Subject: Request for remedial action — EPT panel [reference]
Dear [technical contact or EPT coordinator],
I am writing on behalf of [laboratory full name] of [Australian address] regarding EPT panel [reference], issued on [date] and reported on [date].
Our records show [state the result precisely]. We request a technical review because [describe the discrepancy in neutral, factual terms].
The laboratory has reviewed [material receipt and storage records, transport documentation, equipment logs, the relevant SOP version and staff rosters]. We can provide the listed supporting documents, which contain no patient-identifiable information.
Please confirm receipt; advise whether the provider considers the result valid; explain the validation checks supporting the reported result; and outline any remedial action available under [contract or programme]. If a deficiency is confirmed, please propose a corrective action plan, responsible roles, completion dates and a reassessment method.
Please send a written response by [date] and identify the appropriate contact for follow-up. [Specify any return or storage requirements for outstanding proficiency materials.]
Yours sincerely,
[name, position, authorised contact details]
Replace every placeholder with verified information, and avoid adding accusations that the evidence does not support. If the concern involves several panels or late deliveries, summarise the sequence in the body and enclose the detailed chronology as an attachment.
Send the letter from an authorised representative and keep a signed copy with the original report, attachments and delivery evidence. If panels, slides or cultures remain at the laboratory, identify them clearly and obtain the provider’s instructions before returning or disposing of them. Maintain confidentiality throughout the review.
Reviewing causes and agreeing on corrective action
Review the issue against people, processes, equipment, materials and information before deciding what the provider should correct. For example, a late panel may indicate a dispatch problem, while an unexplained positive result may require a closer look at interpretation, incubation or the reference result. Root-cause analysis should test possibilities rather than settle on the most convenient explanation.
Ask what the provider’s agreement permits it to do. Some providers can review scoring, provide explanatory records, arrange re-examination or offer additional proficiency panels. Local training, SOP revision, equipment maintenance and competency assessment may remain the laboratory’s responsibility. The response should identify which organisation owns each action.
For a wider consistency check, the GLI’s peer-review SOP guidance supports structured comparison of policies and procedures across laboratories. A cross-review involving experienced staff from interstate services can help distinguish an isolated technical issue from a gap affecting several sites.
Monitoring action, reassessment and closure
Turn the provider’s response into a controlled action plan. Each commitment should have an owner, completion date, required evidence and a forum for review. Assign responsibility to the provider or laboratory explicitly, and calendar the agreed review date rather than waiting for informal updates.
Define how success will be demonstrated. This may include a corrected report, documented competency assessment, revised SOPs, verified equipment maintenance or satisfactory performance in a subsequent panel. Where remedial action changes test results or reporting arrangements, confirm how affected findings will be communicated and whether an additional local risk assessment is required.
Use the GLI Quality Tool’s continual improvement resources to connect the corrective action with wider quality-system work. Capture lessons in relevant procedures, communicate them to affected staff and incorporate the outcome into internal audits, management review and the laboratory’s quality management system.
Close the issue only after the agreed evidence has been reviewed and accepted. A written closure should record the final provider position, actions completed, responsibilities accepted by each party and any remaining monitoring. Retain that record with the original correspondence so the same concern is not repeatedly reopened without new evidence.
Sending the request and securing a response
Send the final letter by a channel your provider reliably monitors, commonly email with a PDF attachment. Use tracked courier delivery when originals, confidentiality controls or your service agreement require it. Include a contents list, label attachments clearly and verify that dispatch occurred within the agreed submission period.
If no acknowledgement arrives, follow up courteously on the agreed date. In everyday Australian laboratory communication, a brief “just following up” note is usually more effective than an accusatory message. State the original sending date, quote the requested response date and ask the provider to confirm receipt and the next action.
Before issuing the letter, check it against the GLI Quality Tool’s phase-specific checklists and ensure the quality manager has approved the evidence. Issue the request, diarise the response date and record delivery. Seek written agreement on corrective action, named ownership, reassessment and closure so the TB laboratory can demonstrate that the concern was handled through its quality management system.
