Prototype client story · Diagnostics
From analyser output to clinical information without re-keying the result.
Meridian Diagnostics Group had modern laboratory equipment but too much of the information flow around it still depended on manual entry, printed worksheets and reconciliation. This fictional story shows integration turning instrument output into structured clinical workflow.
Project summary
The instruments were digital. The workflow between them was not.
Meridian Diagnostics Group is a fictional diagnostic provider operating three laboratory locations and a central reporting team. Across chemistry, haematology and selected specialist testing, the business had accumulated analysers from different manufacturers and generations.
Most instruments produced digital results, but the surrounding workflow varied. Some orders were entered directly at the analyser, some patient context was re-keyed from the LIS, and some results were printed or exported before being manually confirmed in the clinical system.
The fictional V3C engagement focused on the information path around the instruments: order context into the device, result data out, validation in the LIS and controlled release into the wider clinical information environment.
Challenge
Manual data movement was hiding inside an otherwise automated laboratory.
The laboratory had invested in automation at the analytical stage, yet staff still carried information between systems. That created avoidable work and made exception handling harder to see. A result could be technically complete at an analyser while the LIS still showed the order as pending.
The integration challenge was complicated by different instrument interfaces, different data fields and tests that required different validation rules. A single generic connector would not solve the workflow unless the organisation also defined how orders, patient identity, units, flags, reruns and corrected results should behave.
Operating environment
Three laboratories, sixteen connected analysers and one result-governance model.
The fictional scope covers chemistry and haematology instruments, a LIS, central patient/order context and controlled result release.
V3C uses an integration layer to translate device-specific exchanges into consistent institutional workflow. Connected instruments receive the relevant order context where supported and return structured results for validation rather than relying on staff to reproduce values manually.
- 3 laboratory locations
- 16 connected analysers
- Order-to-instrument context where supported
- Structured result transfer into the LIS
- Exception and audit handling
V3C approach
Integrate the workflow, not just the serial port or network socket.
The technical connection is only one part of the design. V3C first defines which system owns the order, how the device identifies the specimen, what result fields are accepted, which flags require human review, and what happens when a test is rerun or corrected.
Device-specific interfaces then map into that operating model. The LIS remains the validation and release environment; the integration layer reduces unnecessary re-keying while preserving laboratory control over what becomes a clinical result.
Monitoring is treated as part of the service. A failed connection, unmatched specimen or rejected message has to become visible to the laboratory team rather than disappearing inside middleware logs.
Architecture
Order context in. Structured result out.
Order + patient context

Analyser
Result + flags
LIS validation
Authorised clinical access
How it connects
The integration layer is highlighted because it standardises exchange between heterogeneous instruments and the LIS while validation remains under laboratory control.
Prototype architecture showing order context passing through an integration layer to an analyser, structured result and flags returning to LIS validation, then authorised clinical access.
Implementation
Each instrument became a small integration project inside one common operating model.
2. Canonical mapping
Create consistent institutional mappings for patient, specimen, test, result, unit, status and exception fields.
3. Instrument onboarding
Connect analysers in controlled waves, validate normal and abnormal result paths, reruns, corrections and downtime behaviour.
4. Operational monitoring
Expose interface health and unmatched transactions so laboratory teams can resolve exceptions without searching technical logs.
Prototype outcome snapshot
What the finished story could quantify.
All figures below are invented for this prototype and demonstrate the level of specificity a published case study should aim for when verified evidence exists.
3laboratory locations in the prototype
16analysers connected
74%result records transferred without manual re-entry
61%reduction in result-reconciliation tasks for connected tests
Operational effect
The laboratory did less transcription and more exception management.
The fictional operating change is intentionally practical. Connected tests move from analyser to LIS as structured data, so staff no longer spend the same amount of time copying routine values between screens. The work shifts toward reviewing flags, resolving unmatched specimens and validating results that genuinely need attention.
The central team also gains a clearer view of interface health across locations. A disconnected analyser becomes an operational exception that can be seen and assigned rather than being discovered only when results appear late.
The prototype demonstrates how V3C should write about integration: not “we connected sixteen devices,” but what the connection changed in the information flow and which controls made that change safe.
“The useful change was not that the analysers could send data. It was that the laboratory finally had one controlled path from order to validated result.”Fictional Laboratory Director, Meridian Diagnostics Group
