Laboratory follow-up workflow¶
The lab workflow converts an evidence gap into controlled work and returns the observed result to the decision system. Each transition produces a distinct artifact so scientific advice cannot quietly become execution authority and a completed assay cannot automatically become decision-grade evidence.

Plan work that can answer the question¶
- Start from a governed program, evidence bundle, and explicit decision or evidence gap. Build an advisory plan and retain the rationale for every recommended assay.
- Validate contrasts, controls, replication, blocking, pairing, sample identity, and expected power. Add randomization, fractionation, multiplex, QC, plate, carryover, and protocol details where the assay requires them.
- Build assay dependencies and reject unknown, self-referential, or cyclic edges. Separate gate assays from supporting assays.
- Rank information gain against cost, material, capacity, turnaround, and operational burden. Deferred assays remain visible in the schedule report.
Authorize an executable handoff¶
- Select one batch and declare available sample kinds and operational resources. Run the readiness surfaces; do not treat inventory as review clearance.
- Confirm required controls, sample lineage, protocol attachments, failure caveats, instrument method, and preflight checks.
- Build the executable plan, risk assessment, and canonical artifact envelope. Verify the envelope immediately before export.
- If a target LIMS cannot represent a field, publish the mapping and loss report with the export. Never hide flattened notes, omitted constraints, or changed identifiers.
- Refuse the handoff when evidence, controls, authority, or feasibility is insufficient. Refusal is an operational safety result.
Capture and return the outcome¶
- Record assay result state, QC state, replicate values, dispersion, normalization, censoring, interpretation confidence, protocol deviations, and failure class.
- Evaluate the declared acceptance rule and distinguish technical, reproducibility, biological, and inconclusive outcomes.
- Build batch failure triage, reliability assessment, readiness matrix, and rerun plan before evidence promotion.
- Promote only eligible outcomes under a named policy. Preserve blocked outcomes and the reason they were excluded.
- Reconcile requested versus observed value and send evidence records, claim belief deltas, missing requested assays, and operational lessons back to knowledge and intelligence without rewriting the original plan.
