Diagnostic laboratories handle a large amount of information every day—from patient registration and test orders to sample collection, result processing, reporting, billing, and report delivery.
Managing these activities manually can become difficult as the number of patients and tests increases. A Laboratory Information System (LIS) helps laboratories digitize and organize these workflows through a centralized software platform.
In 2026, modern LIS solutions are going beyond basic laboratory record management. They can connect patient information, sample tracking, laboratory testing, reporting, billing, analyzers, quality workflows, and digital communication into a more integrated system.
This guide explains what an LIS is, how it works, its key features, benefits, LIS vs LIMS, and what diagnostic laboratories should consider when choosing an LIS in 2026.
What Is a Laboratory Information System (LIS)?
A Laboratory Information System (LIS) is software designed to manage and organize information and workflows within a medical or diagnostic laboratory.
An LIS can help laboratories manage the complete testing lifecycle:
Patient Registration → Test Order → Sample Collection → Sample Processing → Result Entry → Verification → Report Generation → Report Delivery
Depending on the system, an LIS may also support:
- Patient management
- Test management
- Sample tracking
- Barcode management
- Pathology reporting
- Analyzer integration
- Quality control
- Billing
- Inventory
- Doctor/referral management
- Digital report delivery
- Laboratory analytics
The exact features vary between LIS providers and laboratory types.
Why Do Diagnostic Labs Need an LIS?
Diagnostic laboratories deal with many interconnected processes. When these processes are managed manually or through separate systems, several problems can occur.
Common challenges include:
- Repeated manual data entry
- Difficulty tracking samples
- Delayed reporting
- Data duplication
- Billing errors
- Difficulty locating previous reports
- Manual report distribution
- Limited visibility into laboratory performance

An LIS can bring these workflows together and create a centralized source of laboratory information.
How Does an LIS Work?
A typical LIS workflow can be divided into several stages.
Step 1: Patient Registration
Patient information is entered into the system.
Step 2: Test Order
The required laboratory tests or packages are selected.
Step 3: Sample Collection
The appropriate sample is collected from the patient.
Step 4: Sample Identification
The sample can be identified using a unique ID or barcode, depending on the laboratory’s setup.
Step 5: Sample Processing
The sample is sent to the appropriate laboratory department for processing.
Step 6: Result Entry or Analyzer Integration
Results can be entered manually or transferred from compatible laboratory analyzers through supported integrations.
Step 7: Result Verification
Authorized laboratory professionals review the results.
Step 8: Report Generation
The system generates the laboratory report based on the configured format.
Step 9: Report Delivery
The final report can be delivered through supported digital channels such as a patient portal, email, SMS, WhatsApp, or download link.
10 Key Features of Laboratory Information System Software
1. Patient Management
An LIS should maintain centralized patient information.
This may include:
