Choosing the right **Laboratory Information System (LIS) is an important decision because the system directly affects sample processing, reporting accuracy, turnaround time, quality control, and communication with clinicians. Instead of choosing a platform based only on features or price, laboratories should evaluate how well it fits their actual workflows and future requirements.
Start With Laboratory Workflow
First, document the complete testing process—from patient registration and order entry to sample collection, accessioning, testing, validation, reporting, and result delivery.
The LIS should support the laboratory's specific disciplines, such as chemistry, hematology, microbiology, molecular diagnostics, or pathology. A system that works well for one type of laboratory may not be suitable for another.
Evaluate Instrument and EHR Integration
Interoperability should be a major selection criterion. The LIS should integrate with laboratory analyzers, hospital information systems, electronic health records, billing systems, reference laboratories, and other applications.
Look for support for standards such as HL7 and FHIR, while also checking whether the vendor has successfully integrated the exact analyzer models used by the laboratory. Laboratory interoperability frameworks specifically address communication between instruments, middleware, LIS, and clinical systems.
A practical demonstration is better than a feature-sheet claim: ask the vendor to show an order moving from the clinical system to the LIS, reaching the analyzer, and returning as a validated result.
Check Automation and Workflow Management
A modern LIS should reduce manual data entry wherever safely possible. Useful capabilities include barcode-based specimen tracking, automatic result capture, reflex testing, autoverification, configurable rules, critical-value alerts, and turnaround-time monitoring.
Automation can reduce repetitive work while improving consistency, but laboratories should ensure that rules are configurable and that manual overrides are properly recorded.
Focus on Security and Compliance
Laboratory systems contain sensitive patient and diagnostic information. Evaluate role-based access, authentication, encryption, audit trails, backup, disaster recovery, data retention, and secure data exchange.
Security should cover both the application and its integrations. HL7 FHIR guidance, for example, emphasizes secure communications, authentication, authorization, and auditing around exchanged healthcare data.
Consider Reporting and Quality Management
The LIS should provide useful operational and clinical reporting rather than simply generating patient reports.
Look for dashboards and reports covering:
- Turnaround time
- Sample status
- Pending tests
- Critical results
- Quality-control activity
- Analyzer performance
- Workload
- Rejected or recollected samples
- Productivity
These capabilities help laboratory managers identify bottlenecks and continuously improve operations.
Evaluate Scalability and Usability
The system should remain practical as testing volume, users, locations, and instruments increase. If the laboratory operates multiple branches, check whether the LIS can support centralized management while maintaining appropriate site-level workflows.
Usability is equally important. A technically powerful system can still fail if technicians, pathologists, and administrative users find it difficult to operate.
Calculate the Total Cost of Ownership
Do not compare vendors only on license or subscription price. Consider implementation, analyzer interfaces, data migration, customization, training, support, infrastructure, upgrades, and ongoing maintenance.
A five-year total-cost calculation usually provides a more realistic comparison between platforms.
Test Before Making the Final Decision
A proof of concept is one of the best ways to evaluate an LIS. Give shortlisted vendors real laboratory scenarios and ask them to demonstrate the complete workflow.
The evaluation team should ideally include laboratory professionals, pathologists, IT teams, quality/compliance staff, and management. This prevents the decision from being based only on technical or financial considerations.
Final Thought
The right LIS is not necessarily the platform with the largest number of features. It is the system that provides the best combination of workflow fit, interoperability, automation, security, usability, scalability, reporting, vendor support, and total cost of ownership.
Labs should therefore create a clear requirements checklist, score vendors objectively, validate integrations with their actual equipment, and conduct a real-world demonstration before making the final decision. This approach reduces implementation risk and increases the chances that the LIS will deliver measurable improvements in laboratory efficiency and reliability.
