Definition
What is a Laboratory Information System (LIS)?
Understanding the foundational role of LIS software in modern healthcare and clinical laboratory operations.
A Laboratory Information System (LIS) is a healthcare software solution that processes, stores, and manages patient data related to laboratory processes and testing enabling providers and lab professionals to coordinate workflows, maintain quality control, and deliver accurate results across clinical disciplines.
— Clinically accepted definition · Healthcare IT Standards 2025
At its core, a Laboratory Information System (also called an LIS system or LIS software) serves as the central nervous system of a modern clinical laboratory. It connects test ordering, sample tracking, analyzer interfaces, result reporting, and billing into a single, unified digital environment.
Unlike general hospital information systems, an LIS is purpose-built for the unique regulatory, analytical, and patient safety requirements of the laboratory. It tracks, stores, and continuously updates clinical details about a patient during a provider visit and preserves that data for longitudinal reference, empowering smarter, faster clinical decisions.
Workflow
How Does LIS Software Work?
From the moment a test is ordered to the delivery of actionable results, the LIS orchestrates every touchpoint in the clinical laboratory lifecycle.
01
Test Order Intake & Patient Registration
The LIS software system receives test orders electronically from clinicians, physicians, or hospital information systems. Patient demographic and insurance data is captured and validated against existing records, eliminating duplicate entries and reducing registration errors before any specimen is collected.
02
Specimen Collection & Chain-of-Custody Tracking
Labels are auto-generated with barcodes or QR identifiers the moment an order is placed. Throughout collection and transport, the LIS maintains an unbroken chain of custody recording who collected the sample, when, and where ensuring regulatory compliance and eliminating misidentification risk.
03
Analyzer Integration & Automated Processing
The LIS system interfaces bidirectionally with laboratory analyzers across hematology, chemistry, immunology, microbiology, toxicology, and other disciplines. Orders are automatically sent to the correct analyzer; results are received and processed in real time, eliminating manual data entry and accelerating turnaround times.
04
Quality Control, Rules Engine & Validation
Built-in decision-support rules evaluate each result against configurable reference ranges, delta checks, and critical value thresholds. Anomalous results are automatically flagged for technologist review, ensuring every reported value meets clinical quality standards before it reaches the ordering provider.
05
Result Reporting & EHR/HIS Transmission
Validated results are transmitted automatically to the Electronic Health Record (EHR), hospital information system (HIS), practice management platform, or patient portal. Critical values trigger real-time alerts to ordering providers, dramatically reducing the time between test completion and clinical action.
06
Billing, Compliance & Audit Trail
The LIS software system automatically generates charge capture data tied to performed tests, reducing billing lag and improving reimbursement rates. A comprehensive, timestamped audit trail satisfies CAP, CLIA, HIPAA, and other regulatory requirements providing evidence-ready documentation for inspections and accreditation.
Comparison
LIS vs. LIMS — What's the Difference?
Laboratory Information System (LIS) and Laboratory Information Management System (LIMS) are terms often used interchangeably but they were designed for different environments and priorities. Here's how they compare.
| Dimension | LIS Laboratory Information System | LIMS Lab Information Management System |
|---|---|---|
| Primary Focus | Patient-centric workflows; personal, demographic, and clinical health data associated with diagnostic testing | Sample-centric workflows; tracking samples, batches, and quality data independent of a specific patient identity |
| Typical Setting | Clinical and anatomic pathology laboratories, hospitals, physician offices, urgent care, reference labs | Research labs, environmental labs, food & beverage testing, pharmaceutical, and industrial quality labs |
| Core Data Model | Patient → Encounter → Order → Result → Report; longitudinal patient record maintained | Sample → Test → Result; data organized by sample batch or project rather than patient record |
| Regulatory Compliance | CLIA, CAP, HIPAA, HL7, IHE, FDA 21 CFR Part 11 (clinical focus) | ISO 17025, GLP, GMP, FDA 21 CFR Part 11 (research/industrial focus) |
| EHR / HIS Integration | Deep, bidirectional HL7/FHIR integration with EHR and HIS systems is a core requirement | EHR integration is secondary; typically integrates with LIMS-adjacent platforms or ERPs |
| Critical Value Alerting | Essential real-time alerts to ordering providers for patient safety | Not typically required; focus is on out-of-specification flagging for quality control |
| Billing & Reimbursement | Integrated charge capture and CPT coding tied to ordered tests | Generally not applicable; costs tracked through project or contract management |
| Today's Reality | Modern platforms increasingly blur the boundary offering configurable features that serve both patient-centric (LIS) and sample-centric (LIMS) workflows within a single unified system. | |
Bottom line: If your laboratory's primary mission involves diagnosing and treating patients, you need a dedicated Laboratory Information System (LIS). If your work is primarily research, environmental, or industrial testing, a LIMS is the better fit. Many modern LIS software platforms now support both contact us to find the right match for your laboratory.

Frequently Asked Questions
Common Questions About Laboratory Information Systems
What does LIS stand for in healthcare?
In healthcare, LIS stands for Laboratory Information System a specialized software platform designed to receive, process, manage, and report patient-related laboratory test data within clinical and anatomic pathology environments. The LIS connects every stakeholder in the diagnostic chain, from the ordering physician to the laboratory technologist to the patient, through a unified, compliant data infrastructure.
What is the difference between an LIS and an EHR?
An Electronic Health Record (EHR) is a broad patient record system capturing clinical notes, diagnoses, medications, and care history. A Laboratory Information System (LIS) is a specialized tool focused exclusively on laboratory workflow specimen tracking, analyzer integration, quality control, and result reporting. The two systems are complementary: the LIS generates the laboratory data that feeds into the EHR. Modern LIS software integrates with all major EHR platforms via HL7 and FHIR standards.
Is LIS software available as a cloud-based (SaaS) solution?
Yes. Modern LIS software systems are increasingly offered as cloud-based SaaS (Software-as-a-Service) platforms.
