Major LIS Platforms We Integrate
Laboratory information systems vary widely in architecture, interface capabilities and configuration. Hospital labs often run LIS modules tightly connected to their EHR, while reference and outreach labs may use standalone systems. Each platform has different interface tools, specifications and constraints. Understanding the platform first shapes realistic plans. Our wider lab integration services cover reference labs, while this page focuses on laboratory information system integration inside and around hospital and outreach laboratories.
Sunquest Integration
Sunquest laboratory systems are widely used in hospital laboratories. Integrations typically use HL7 interfaces for orders, results and ADT, plus instrument connectivity, with careful attention to site-specific configuration and test build.
Epic Beaker Integration
Epic Beaker is Epic's laboratory module, closely connected to the Epic EHR. Beaker integrations often involve reference lab interfaces, instruments and outreach workflows, coordinated with the hospital's Epic analysts and interface teams.
Oracle Health Millennium Lab
Oracle Health Millennium includes laboratory capabilities integrated with its EHR. Integrations cover reference lab orders and results, instruments and outreach, following Millennium interface processes and customer configuration standards. Coordinate closely with customer teams.
Standalone and Outreach LIS Platforms
Reference and outreach labs often run standalone LIS platforms serving many external clients. These integrations connect to numerous practice EHRs, requiring scalable interface designs, client onboarding processes and compendium distribution.
Choosing the Right Approach
Confirm the LIS platform, version, interface engine and connected systems before designing interfaces. Platform capabilities and hospital configuration often determine the approach more than preferences or generic best practices. Document every assumption.
Order and Result Workflows
The core of LIS integration is the order-to-result workflow. Orders flow from EHRs or outreach clients into the LIS, specimens are collected and processed, and results return to ordering systems. Each step needs accurate patient identity, order numbers, specimen tracking and status handling. Our HL7 integration engineers build these workflows with acknowledgements, error queues and monitoring, so orders are processed reliably and results reach the right charts. Each step is explained below.
Inbound Orders
Orders arrive from EHRs, outreach clients or reference lab relationships as HL7 order messages. The LIS must validate patients, tests, specimens and providers, rejecting incomplete orders with clear, actionable reasons.
Specimen Tracking
Specimen collection, receipt and processing events need accurate timestamps and identifiers. Integration with labeling and tracking workflows prevents lost specimens and supports turnaround time monitoring across laboratory sections. Timestamps must be accurate.
Result Delivery
Results return as HL7 result messages with values, units, ranges, flags and status. Preliminary, final and corrected results must update correctly, and critical values must trigger urgent notification workflows. Escalation must be reliable.
Reference Lab Send-Outs
Hospital labs send some tests to reference labs such as Quest or Labcorp. Send-out interfaces must manage orders, results and tracking, so results return to the originating LIS and patient chart.
Billing Integration
Completed tests generate charges for billing systems. Accurate charge interfaces, with correct codes and quantities, prevent lost revenue and support compliant laboratory billing for inpatient, outpatient and outreach services. Reconcile charges regularly.
Instrument Interfaces and LOINC Mapping
Instrument interfaces connect analyzers to the LIS, often through middleware that manages worklists, results and quality rules. These connections reduce manual entry and speed turnaround. At the same time, LOINC mapping gives results standard codes, enabling interoperability, trending and reporting. Both areas require laboratory expertise, not just interface development skills. Accurate mapping also supports EHR/EMR integration, where results must display consistently in clinical charts. Both areas are explained below in practical detail.
Instrument Connectivity
Analyzers connect to the LIS directly or through middleware, using protocols such as ASTM or HL7. Interfaces transfer worklists and results, reducing manual entry and transcription errors in laboratory sections.
Laboratory Middleware
Middleware sits between instruments and the LIS, applying rules, managing quality control data and supporting autoverification. Integration design must consider which logic lives in middleware and which lives inside the LIS.
Autoverification Rules
Autoverification releases results automatically when they meet defined criteria. Rules must be designed and validated carefully by laboratory leadership, because errors can release inaccurate results directly to clinicians. Document every rule change.
LOINC Mapping
Map local test and result codes to LOINC using specimen, method, property and units. Clinical laboratory review is essential, because incorrect LOINC codes can merge results that should remain separate.
Maintaining Mappings
New tests, method changes and instrument replacements require mapping updates. Establish change processes, so new tests are mapped before go-live and unmapped results are monitored and resolved promptly. Assign clear owners.
Reflex Testing Logic and Our LIS Services
Reflex testing automatically adds tests based on initial results, such as ordering confirmatory testing when a screening result is positive. Reflex logic affects orders, billing, results and clinician communication, so interfaces must handle added tests correctly. We design and test these workflows carefully. Our LIS integration services also include LIS integration support for existing platforms, upgrades, migrations and ongoing monitoring across laboratory interfaces and connected systems. Each area is explained below.
Reflex Test Handling
Interfaces must communicate reflexed tests to ordering systems, so clinicians see why additional tests appeared. Results and charges for reflexed tests must link correctly to the original order. Communication must be clear.
Billing for Reflex Tests
Reflexed tests often generate additional charges. Interfaces must send accurate charges with correct codes, supporting compliant billing and avoiding revenue loss from unbilled or incorrectly billed tests. Audit reflex charges regularly.
LIS Upgrades and Migrations
LIS replacements and upgrades require interfaces to be rebuilt, tested and cut over carefully. Parallel testing and validation protect patient care while laboratories transition between systems. Rollback plans are always tested first.
Outreach Client Onboarding
Outreach labs connect to many practice EHRs. We build repeatable onboarding processes, templates and testing checklists, helping labs connect new clients quickly without custom work for every practice. Templates speed every rollout.
Monitoring and Support
We monitor laboratory interfaces for errors, delays and volume changes, supporting laboratories with fast issue resolution, upgrade support and documentation their teams can use confidently. Our Mirth Connect consulting team handles engine-level monitoring.
Frequently Asked Questions
What is LIS integration?
LIS integration connects laboratory information systems with EHRs, instruments, reference labs and billing systems. It covers inbound orders, specimen tracking, result delivery, instrument connectivity, LOINC mapping, reflex testing and charge interfaces, ensuring laboratory data moves accurately and securely between all connected systems and teams.
Which LIS platforms do you integrate with?
We integrate with major LIS platforms, including Sunquest, Epic Beaker and Oracle Health Millennium laboratory capabilities, plus standalone and outreach LIS systems. Each platform has different interface tools and constraints, so we confirm platform, version and configuration before designing integrations and testing plans.
What is Epic Beaker integration?
Epic Beaker integration connects Epic's laboratory module with instruments, reference labs, outreach clients and other systems. Because Beaker is closely connected to the Epic EHR, integrations require coordination with the hospital's Epic analysts and interface teams, following Epic configuration and interface standards.
How are laboratory instruments integrated with an LIS?
Instruments connect to the LIS directly or through laboratory middleware, using protocols such as ASTM or HL7. Interfaces exchange worklists and results, while middleware can apply rules, quality control and autoverification. Integration reduces manual entry, speeds turnaround and improves accuracy in laboratory workflows.
What is reflex testing in LIS integration?
Reflex testing automatically adds tests based on initial results, such as confirmatory testing after a positive screen. Interfaces must communicate reflexed tests to ordering systems, link results to original orders and send accurate charges, so clinicians understand added tests and billing remains compliant.
Why is LOINC mapping important for laboratories?
LOINC mapping gives laboratory results standard codes, enabling consistent display, trending, reporting and data sharing across organizations. Accurate mapping requires laboratory expertise, because specimen, method and units determine correct codes. Incorrect mapping can merge different tests or split identical ones, affecting clinical interpretation.
