Laboratory integration moves orders to the performing lab and results back into the clinical record as discrete, coded, correctly attributed data. It handles messaging, mapping, routing, and corrections. It does not interpret results, flag clinical significance beyond configured rules, or decide who is notified of a critical value.
Lab interfaces look routine until you meet corrected results, reflex testing, and a reference lab whose compendium changes without notice. Those are where patient safety incidents live, not in the initial ORU build. Taction builds lab interfaces where amendments, unmapped codes, and delivery failures are handled deliberately rather than discovered during an incident review.
Our experts are ready to understand your business goals.
The work that determines success is mapping discipline and failure handling. An unmapped analyte must land somewhere a human sees rather than silently defaulting, and an undelivered result must raise an alarm rather than sitting in a queue. Where the requirement is building or replacing the laboratory system itself, our laboratory information system development work covers that, and this page covers connecting systems that already exist. We also scope compendium maintenance as ongoing operational work from the start, because mapping is never finished, and any estimate that treats it as configuration has mispriced the engagement.
Channels, transformation, acknowledgement, retry, and queue management delivered on Mirth Connect or your existing platform. Engine configuration includes alerting on queue depth and transport failure. Retry behaviour is specified rather than left to defaults.
Analyte mapping, unit normalisation, and reference range handling against each lab’s compendium. Unmapped codes route to a review queue with a named owner rather than defaulting silently. Review is clinical as well as technical.
Connections to national and regional reference labs following each lab’s interface specification. Compendium updates arrive from the lab and are treated as recurring maintenance work. Their specification governs, and we build to it.
Results routed to ordering provider, covering provider, and the record, with delivery confirmation. Delivery failure raises an operational alert, since an undelivered abnormal result is a safety event. Confirmation is tracked per recipient.
Corrected results supersede originals with both versions retained and the change visible. Amendment visibility is verified in the chart, not just in the interface log. Behaviour is agreed in writing before any build.
Electronic ordering with compendium-driven test selection, ask-at-order-entry questions, and specimen labelling. Order accuracy at entry removes most downstream accessioning rework. Ordering integrates with the chart through our EHR and EMR integration services.
Lab integration is order transmission, specimen and status handling, and result delivery, with a coding layer that makes results comparable over time. It sits inside a broader healthcare integration programme and uses the same engine and messaging foundations as our general HL7 integration services. What makes lab work distinctive is the coding and correction burden: results are longitudinal data that clinicians trend for years, so a mapping error or a missed amendment persists long after the interface is declared finished. A mapping decision made in week three is still shaping data years later.
Orders travel to the performing lab with priority, specimen details, and collection information. Order messaging must carry enough context for the lab to accession without a phone call. Missing context creates accessioning calls.
Results return as HL7 result messages carrying values, units, reference ranges, and abnormal flags per analyte. Discrete results are the goal, since a scanned report cannot be trended. Scanned reports are a fallback.
Analytes map to LOINC so the same test from two labs trends as one series. Code mapping is manual, ongoing work rather than a one-time configuration task. Each new lab brings its own catalogue.
Labs correct and amend results after release. Correction handling must supersede the original visibly in the chart, and getting this wrong is a genuine safety problem. Both versions are retained in the record permanently.
Labs add tests based on initial findings, producing results nobody ordered explicitly. Reflex results need attribution, ordering provider assignment, and a delivery path. Interfaces assuming an existing order for every result drop these.
It does not interpret a result, diagnose, or judge clinical significance. Interpretation belongs to the clinician, and critical value notification follows rules your clinical leadership sets. Configured rules are policy, not clinical judgement.
We publish no figures on turnaround time, transcription error reduction, or result delivery rates, because those depend entirely on your labs, your volumes, and your current process. What we deliver is instrumentation so your team measures impact against its own data. The dependable benefits are structural: discrete coded results that trend, corrections that are visible, and failures that raise alarms. None of those is exciting, and each of them is what distinguishes a working lab interface from one that appears to work. Judge a lab interface by its failure handling rather than by its go-live date.
Coded, discrete results let a clinician see a series rather than a stack of documents. Trendable data is the whole clinical point of doing this work properly. Units and ranges travel with each value.
Amended results supersede originals in the chart with history retained. Visible corrections prevent a clinician acting on a value the lab has already withdrawn. Superseded values cannot be mistaken for current ones.
Undelivered results, transport failures, and queue backlogs alert an owner. Failure visibility is what converts an interface from a hopeful assumption into an operational asset. An undelivered abnormal result is treated as an incident.
New or changed analytes land in a review queue rather than defaulting to something plausible. Mapping discipline prevents silent corruption of longitudinal data. Queue volume is reported, since a rise usually signals a compendium change.
Compendium-driven ordering with required questions reduces accessioning queries and specimen rejections. Order completeness is a lab satisfaction issue as much as a clinical one. Specimen rejections and repeat draws fall as a consequence.
LOINC mapping never finishes, because compendia change. Ongoing mapping is a recurring operational cost, and any vendor implying otherwise has not run one long. Budget it annually rather than treating it as project scope.
We sequence around compendium quality and correction handling, since those are the two things that decide whether the interface is safe two years from now. Discovery is paid and time-boxed and produces an itemised fixed-scope estimate with a build or configure recommendation. Where a reference lab offers a certified interface into your EHR, using it usually beats building one, and we say so. Delivery runs in short increments validated against the lab’s test environment with real sample messages. We also test with the malformed messages your labs actually send rather than only with clean samples.
We compare each lab’s compendium against your existing catalogue and coding. Mapping volume is counted rather than estimated, because it dominates the timeline. That count is the single best predictor of project duration.
We define behaviour for corrections, amendments, cancellations, and reflex additions before building. Correction design is agreed with clinical and lab stakeholders in writing. Sign-off comes from clinical leadership, not from the interface team.
Order and result channels, transformation, acknowledgement, and routing built in increments. Sample validation uses real lab messages, including the malformed ones they actually send. Clean sample messages prove less than teams expect.
Queue monitoring, delivery confirmation, unmapped code queues, and alerting completed before go-live. Failure paths are a go-live condition on our projects rather than a later phase. Alert recipients are named individuals, not distribution lists.
We work through the performing lab’s test process and message rounds with your team. Lab timelines are set by their interface group and sequenced around accordingly. Their queue is not something we can shorten.
Parallel running, then cutover with heightened monitoring and a runbook for mapping maintenance. Handover leaves your team able to onboard the next lab unaided. Your team can then onboard the next lab unaided.
We build lab interfaces on standards-based messaging with our clinical data integration practice governing normalisation and provenance. Compliance covers HIPAA safeguards, audit trails sufficient to reconstruct what a clinician saw and when, and clear separation between configured rule behaviour and clinical judgement. Critical value handling is a clinical policy we implement deterministically. We do not build probabilistic prediction into notification paths, because a missed critical value is not an acceptable statistical outcome. Every rule we implement is documented as your clinical policy, so a change of policy is a configuration change rather than a rebuild.
Order, status, and result messages with application acknowledgement processing and retry. Acknowledgement handling distinguishes transport success from acceptance by the receiving system. Negative acknowledgements are queued for a person rather than retried indefinitely.
LOINC mapping, unit normalisation, and performing lab recorded per result. Provenance labelling lets a clinician see which lab produced a value before trusting a trend. Two labs’ values are never silently merged into one series.
Notification follows rules your clinical leadership defines, applied deterministically with acknowledgement tracking. Rule enforcement replaces any probabilistic or model-driven approach here. Acknowledgement is tracked so you can prove receipt after the fact.
The interface delivers values, units, ranges, and lab-supplied flags. It does not interpret, diagnose, or grade significance, and clinician judgement governs every action taken on a result. Lab-supplied flags pass through unchanged.
Superseded results are retained with full history and never deleted. Record integrity supports retrospective review and any subsequent case investigation. Retrospective review can reconstruct exactly which value a clinician saw and when.
Queue depth, delivery confirmation, unmapped code volume, and acknowledgement failures monitored with alerting. Operational audit is how you learn about a problem before a clinician does. Thresholds are agreed with your operations team.
We have been building healthcare software since 2013, which is over 12 years, and we have delivered more than 200 healthcare projects. Interface engineering and engine work are core practice here rather than an adjacent service, and we built our own EHR platform, Voyant Health, so result presentation and trending are familiar territory. We are ISO 27001 certified, our leadership brings more than 20 years of personal experience in the field, and we work from four US offices in Chicago, Cheyenne, Austin, and Sacramento. We also say when a lab’s certified interface is better.
Engine configuration, acknowledgement handling, and failure paths are long-standing work for us. Monitoring is part of the build rather than a support upsell later. Alert routing to named owners is included in that scope.
We design amendment behaviour before writing channels. Correction design is where lab interfaces cause harm, and it deserves explicit sign-off rather than assumption. Sign-off is explicit, in writing, before channels are built.
Building Voyant Health means we understand how results must appear, trend, and supersede inside a chart clinicians actually read. Presentation matters as much as transport, and we design for both together.
Taction is ISO 27001 certified, with documented access control, encryption, credential management, and change control that stands up to a security review. Interface credentials and their rotation practice are documented for review.
If a reference lab offers a certified interface into your EHR, we recommend it. That advice loses us work and saves you an interface to maintain forever. It appears in the discovery report.
Four US offices in Chicago, Cheyenne, Austin, and Sacramento, with delivery overlapping your hours during lab test cycles and cutover. Escalation reaches a named delivery lead rather than a support queue.
Lab integration pricing turns on the number of labs, whether ordering is in scope alongside results, and how much mapping your compendia require. The tiers below cover engineering. Third-party licensing, cloud infrastructure, data subscriptions, and hardware are separate from engineering cost and itemised clearly. Interface engine licensing and any connectivity provisioning are vendor line items, and mapping maintenance after go-live is quoted as recurring operational work rather than folded into the build price. Where a lab charges for interface build or certification on their side, that cost is theirs to quote and we flag it early.
$40,000 to $80,000 for an inbound result interface from one lab with mapping, routing, correction handling, failure alerting, and monitoring. One lab, results only, assuming your catalogue is already reasonably coded.
$80,000 to $200,000 for bidirectional order and result interfaces across several labs with mapping layer, reflex handling, delivery confirmation, and operational dashboards. This tier covers most multi-lab ambulatory and community hospital programmes.
Starting at $200,000 for multi-facility routing, many lab connections, a repeatable onboarding template, high volume throughput, and multi-EHR distribution. Lab count and receiving system count drive the figure more than volume.
A paid, time-boxed discovery phase produces a mapping volume count, correction scenario design, build or configure recommendation, and an itemised fixed-scope estimate per lab. The mapping count is yours whether or not we build.
Lab count, mapping volume, order scope, reflex handling, and receiving system count. Compendium quality affects cost more than message volume ever does. A poorly coded catalogue can double the mapping workload alone.
Budget annually for mapping maintenance, compendium updates, monitoring, lab specification changes, and EHR upgrade regression testing. Mapping work continues for the interface’s life. We quote it as recurring operational work rather than project scope.
If your lab interfaces work but nobody can tell you the unmapped code volume or the delivery failure rate, start with an assessment. A paid discovery phase gives you a counted mapping workload per lab, a correction and reflex scenario design, an honest view of what your current interfaces are dropping, a build or configure recommendation, and an itemised fixed-scope estimate. If a lab’s certified interface covers it, you keep the assessment and spend nothing further with us. Talk to our team about which labs you use.
These are the questions interface leads, lab directors, and practice administrators raise before scoping lab work. Several concern the parts that appear small in a requirements document and are not, chiefly corrections and unmapped codes. One concerns whether to build at all, where the answer is often no. Where an answer depends on a specific lab’s specification or your EHR’s existing connections, the mapping assessment in discovery resolves it quickly. The mapping assessment is worth having regardless, because it tells you what your current interfaces are quietly dropping today, before anyone quotes you a build.
If the lab offers a certified interface into your EHR that returns discrete coded results, use it. Custom work earns its cost with many labs, non-standard routing, systems outside the EHR, ordering requirements the lab’s interface does not cover, or monitoring and mapping control your vendor does not provide.
Because each lab’s compendium is its own catalogue, and mapping decides whether two labs’ results trend as one series or two. It is manual clinical and technical work, it must be reviewed rather than guessed, and it recurs as compendia change. Any estimate treating it as configuration is understating the project.
By designing the behaviour before building. A corrected result supersedes the original in the chart with both versions retained and the change visible to clinicians. We verify that in the receiving system rather than in the interface log, because a correction that never reaches the chart is worse than no interface at all.
It routes to a review queue owned by a named person, and it is not silently mapped to something plausible or discarded. Volume in that queue is monitored and reported, because a rising unmapped rate usually means a compendium changed and nobody was told. Silent defaulting is how longitudinal data gets corrupted.
We implement the notification rules your clinical leadership defines, deterministically, with acknowledgement tracking so you can prove a value was received. We do not build probabilistic or model-driven prioritisation into that path. A missed critical value is not an acceptable statistical outcome, so the logic stays explicit and auditable.
Yes, and it needs to. Reflex results arrive without a matching order, so attribution, ordering provider assignment, and delivery path all need explicit handling. Interfaces that assume every result maps to an existing order drop these, and nobody notices until a clinician asks where a result went.
