LIMS Integration Guide: Connecting Your Lab Systems

Your LIMS is only as good as its connections. Here's how to integrate without the integration nightmares.

LIMS integration means connecting your LIMS to other systems—instruments, EMR/EHR, billing, and more. Good integration eliminates manual data entry and reduces errors. Bad integration creates new problems. This guide helps you get it right.

Why Integration Matters

1-3%

Manual transcription error rate

<0.1%

Integrated data capture error rate

  • Every manual data entry is an error opportunity
  • Disconnected systems mean duplicate work
  • Real-time data beats batched data
  • Compliance requires audit trails that cross systems

Types of LIMS Integrations

Instrument Interfaces

Connecting analyzers to LIMS via bidirectional interfaces. Standards: ASTM, LIS2-A2. Typically 2-4 weeks per instrument. Usually the highest-value integration.

What we've seen: Labs often underestimate how many instruments need interfaces. Do inventory first.

EMR/EHR Integration

Connecting to hospital systems using HL7 v2.x or FHIR. Bidirectional order and result flow. Typically 1-3+ months.

What we've seen: EMR integration is harder than vendors suggest. Patient demographic data is often inconsistent.

Billing System Integration

Sending charges and receiving payment info. Revenue flows through here—get it right. Complexity depends on billing system.

What we've seen: Test thoroughly. Billing errors are expensive and hard to fix retroactively.

Integration Standards Explained

StandardUse CaseNotes
HL7 v2.xEMR/EHR, LISMost widely used in healthcare. Message-based.
FHIRModern APIsREST-based, growing adoption. Better interoperability.
ASTM/LIS2-A2InstrumentsStandard for lab analyzers. Well-established.
Custom APIsWhen standards don't fitMore flexible but more maintenance.

Integration Pitfalls to Avoid

Assuming data will be clean—it won't be
Underestimating testing time—plan for 2x what you expect
Forgetting edge cases—cancelled orders, corrections, reruns
Inadequate error handling—what happens when integration fails?
No monitoring—failures should alert someone
Skipping UAT—users find problems developers miss

How Gistia Approaches Integration

We start with workflow requirements, not technology. We coordinate between your existing systems, build for maintainability, and plan for what happens when things fail.
