Reconcile two exports before scheduling culture-result collection Use two test analyses with known sample, vessel and preparation records. Obtain the original exports, the matching analyzer reports and the collection times. The first run should prove the quantity mapping and replay behavior with a small population that can be checked manually. FIRST RUN 1. Choose the source population and supporting records Select the two intended analyses in Historical Results, checking the displayed date range. Export the chosen sample results and retain the matching reports. Collect any required QC evidence and cell images separately. Record the installed software and the exact export headers before mapping. Check: The packet accounts for both analyses and identifies which sample each represents. Missing QC or image evidence remains visible; a sample-result CSV alone does not prove that those separate artifacts were collected.

Make collection time and source identity explicit Match each export entry to the analyzer display and the independently recorded culture collection. Record how the source identifies repeat measurements and later evaluations. Use A-101 and A-102 only as local worksheet labels until the real source identity contract has been established. Check: The proposed key distinguishes two legitimate measurements with the same sample name. A re-export resolves to the existing entry. If the export cannot unambiguously establish that relationship, retain an unresolved mapping rather than inventing identity from row order. 3. Check a density, a percentage and a chemistry result Work through the selected analysis below with its report and preparation record. Read the density scale from the exported unit, establish which corrections the reported result already includes, and map glucose independently. Retain any missing or qualified result with its status. Check: For the fictional case: density is 4,800,000 cells/mL, viability is 96%, and glucose is 3.2 g/L. Lactate has no numeric value. Save the original representation and transformation evidence with each receiving field; one sample-level factor is insufficient to define every quantity. 4. Deliver closed files with deliberate overlap Make one test handoff containing A-101 and a second containing A-101 plus A-102. The transfer owner must define how a consistent export or snapshot becomes a closed file before it enters the watched folder. Include a test where transfer stops halfway; temporary files must not be presented as complete handoffs. Check: After both completed handoffs, the result population contains two analyses, with the repeated delivery attributable. Compare expected source entries, parsed entries, unresolved entries and destination identities. An incomplete transfer should be recoverable without claiming that the missing portion was imported. 5. Check recovery and a later evaluation Interrupt the receiving process after A-101 is retained, then deliver the second handoff again. Separately include a supported later evaluation of A-101’s sample and retain its relationship to the original analysis. Compare the destination history and culture timeline after both tests. Check: Recovery completes the intended population without creating another A-101. The later evaluation remains identifiable under its original collection; it does not silently replace earlier evidence or move the culture’s collection time. Inspect quantities independently These are fictional mapping decisions. Use the actual export units and correction evidence; the instrument’s preparation settings do not define every destination field by themselves. Field: Viable cell density Source evidence: 4.8 × 10^6 cells/mL; correction included Receiving result: 4,800,000 cells/mL; no second preparation factor Field: Viability Source evidence: 96% Receiving result: 96% in a percentage field, not 96 cells/mL Field: Glucose Source evidence: 3.2 g/L Receiving result: 3.2 g/L under its confirmed chemistry basis Field: Lactate Source evidence: Unavailable Receiving result: No numeric value; preserve status Field: Culture collection Source evidence: S-301 collected 09:00 UTC Receiving result: Plot at the collection event; retain analysis at 09:18 separately Expected receiving ledger for the two handoffs Illustrative reconciliation CSV, not Nova’s export format. The actual connector must supply the identity matching and recovery behavior represented here. handoff,source_analysis,receiving_action,expected_analysis_count handoff-01.csv,A-101,create,1 handoff-02.csv,A-101,link repeated delivery,1 handoff-02.csv,A-102,create,2 The ledger has three source entries and two scientific analyses. Keep delivery history as evidence without counting each arrival as another culture measurement. If A-101 changes under the same claimed identity, resolve that conflict before treating the entry as a harmless repeat. PROPOSED RECEIVING CHECKS — NOT EXECUTED CUSTOMER VALIDATION Two files overlap Input: Deliver the worked handoffs, then replay handoff-02.csv. Expected: Two analyses remain. The new arrival is traceable, and its A-101 and A-102 entries resolve to the intended existing results. The density correction is already included Input: Provide the worked 4.8 million cells/mL result and factor 2 with explicit already-corrected evidence. Expected: The destination contains 4,800,000 cells/mL, not 9,600,000. Viability and glucose retain their separately defined quantities. The source contains no valid lactate number Input: Use the unavailable lactate entry alongside valid glucose. Expected: Glucose remains usable under its own rules. Lactate is missing with its source state, and the sample is not presented as a complete numeric analyte panel. A later evaluation shares the original collection Input: Deliver a supported reanalysis with a later evaluation time and the same physical collection evidence. Expected: Both evaluations remain attributable to S-301. The culture timeline still uses the 09:00 collection, and the reviewer can identify the selected evaluation and its supporting evidence. HANDOFF Save the export headers, installed version, identity contract, source reports, collection and preparation evidence, snapshot-completion procedure and three-entry reconciliation. Assign ownership for failed transfers and unresolved results before running unattended collection. Seal then has the context needed for an inspectable culture comparison.
