Sponsor–laboratory worksheet

A practical discrepancy log for sponsors and external laboratories

A browser-local worksheet for recording what differed during an outsourced study without overwriting the original observation, evidence state, decision boundary or accountable review history.

SingularCell Research. Reviewed for source scope, workflow usefulness and unsupported claims. It remains unpublished until the roadmap, cadence and release gates permit a separate publication action.

How to use this resource

Work through the checklist before using the record table. Enter only non-confidential working notes on this public page, then transfer approved information into your organisation's controlled system of record.

Entries stay in this browser page and are not submitted to SingularCell. Download or storage is not implied.

Discrepancy intake checklist

Use these prompts to confirm that the observation, affected version, evidence state, ownership and review boundary are visible before triage begins.

Exact observation capturedRecord what was seen without merging it with a suspected cause or preferred correction.Evidence prompt: Reference the source file, run, message or record containing the observation.
Affected version identifiedName the exact study contract, material, method, result file or report version in scope.Evidence prompt: Provide the stable identifier and version for every affected record.
Evidence state declaredDistinguish evidence that is present, missing, inaccessible, contradictory or awaiting review.Evidence prompt: List the evidence references and the state of each one without adding a pass or fail.
Accountable owner namedAssign the person responsible for triage and the person authorised to review the disposition.Evidence prompt: Record the accountable role and approved organisational record for the assignment.
Decision boundary statedDescribe which decision may be affected and which scientific or regulatory conclusions remain unmade.Evidence prompt: Reference the declared intended use and the review authority for the decision.

Working discrepancy record

Draft a bounded handoff record here, then move approved information into the controlled system your organisation uses for study evidence and change history.

Original observation

Describe only what was observed, including date, stage and source reference.

Affected records and versions

List the exact study, material, method, file or report identifiers potentially affected.

Evidence and missing evidence

Separate available evidence, contradictory evidence and evidence that has not been supplied.

Owners and proposed actions

Name accountable roles, containment steps, evidence requests and proposed corrective actions.

Review and disposition

Record the human review outcome, supporting evidence, unresolved limitations and successor version.

A useful discrepancy record keeps the original observation, its supporting evidence, the affected study version, the accountable owner, the proposed response and the final human review visibly separate.

Record the observation before the explanation

Begin with what was observed, where it appeared and which exact study, material, method, file or result version it affects. Preserve the original wording or evidence reference before adding a proposed cause, interpretation or correction.

This separation matters because a plausible explanation is still an interpretation. The discrepancy log should let a reviewer distinguish the source observation from later analysis, proposed action and final disposition.

Assign one stable discrepancy identifier
Link the exact affected study and evidence versions
Record when and by whom the observation was made
Keep the original observation distinct from interpretation
Classify missing evidence without treating absence as failure

Make ownership and possible impact explicit

Name the sponsor and laboratory owners responsible for triage, evidence collection and review. Record the declared scope that may be affected, while avoiding an unsupported conclusion about biological validity, regulatory significance or result acceptance.

Measurement context and sources of variability can change how an observation should be interpreted. The record should therefore capture the relevant method, instrument, software, handling and control context rather than relying on a short assay label.

Name one accountable triage owner
Name the reviewer who can accept the disposition
Describe the potentially affected evidence and decision
Record relevant method and measurement context
State which impact conclusions remain unresolved

Preserve the review and correction history

Record proposed containment, evidence requests, corrective action and final disposition as separate events with dates and owners. A later correction should point back to the original record instead of silently replacing it.

The final state should say what the accountable reviewer accepted, what evidence supported that decision and what remains limited or unresolved. Closing a workflow item does not prove that the biology passed, that two methods are equivalent or that a regulated requirement was satisfied.

Keep every consequential correction append-only
Attach evidence references to each proposed action
Record who reviewed and who approved the disposition
State remaining limitations and follow-up work
Link any successor study or report version

Limitations

This worksheet is educational workflow guidance and is not a biological protocol, quality-system procedure or regulatory compliance determination.
The FDA source applies to its stated drug CGMP context; this template does not extend those requirements to every research study.
The template does not determine scientific impact, choose corrective action, establish method equivalence or decide whether a result is acceptable.
