Pathology laboratory information systems (LIS) help laboratories manage the full testing workflow, from receiving a sample to producing and delivering the final report. They can reduce manual work and make it easier for laboratory staff to track samples and test information.
Sample Tracking
An LIS can assign a unique identification number or barcode to each sample. Staff can then track where the sample is during the testing process.
It can help monitor:
- Sample collection
- Sample receipt
- Sample preparation
- Testing
- Storage
- Disposal
This reduces the chance of samples being misplaced or mixed up.
Test Processing
Laboratory staff can use an LIS to manage test requests and results.
The system can help with:
- Registering test orders
- Assigning tests
- Sending work to appropriate laboratory sections
- Recording test results
- Flagging abnormal results
- Tracking pending tests
It can also connect with laboratory instruments so that results can be transferred automatically instead of being entered manually.
Patient Records
An LIS can keep laboratory information connected to the correct patient record.
Depending on the system and healthcare setup, it may store:
- Patient identification
- Test orders
- Previous laboratory results
- Sample information
- Test reports
- Doctor or department information
Having this information in one system makes it easier for authorized staff to review a patient's laboratory history.
Reporting
Reporting is one of the main functions of an LIS. Once testing is completed, the system can help generate standardized laboratory reports.
Useful features include:
- Automatic report generation
- Result verification
- Report templates
- Digital report delivery
- Critical-result alerts
- Report history
This can help reduce delays between completing a test and delivering the result.
Workflow Management
Pathology laboratories often handle many samples and different testing processes at the same time. An LIS can organize these activities in a structured workflow.
For example:
Order → Sample collection → Barcode identification → Laboratory processing → Testing → Result verification → Report
Staff can see which steps have been completed and which tasks are still pending.
Quality and Error Reduction
An LIS can also support laboratory quality processes by maintaining records of test activities and changes.
Useful capabilities include:
- Audit trails
- Quality-control records
- Result validation
- Error alerts
- Instrument monitoring
- User activity tracking
Automation can reduce some types of manual data-entry errors, although laboratory staff still need to verify results and follow appropriate procedures.
Integration
Modern laboratory systems may connect with other healthcare systems and equipment.
Examples include:
- Hospital information systems
- Electronic health records
- Laboratory analyzers
- Billing systems
- Patient portals
- Reference laboratories
Integration can reduce duplicate data entry and allow information to move between systems more efficiently.
Conclusion
Pathology laboratory information systems can make daily laboratory work more organized by connecting sample tracking, test processing, patient information, reporting, and workflow management in one system. Features such as barcoding, analyzer integration, automated reports, audit trails, and workflow tracking can reduce repetitive administrative work while helping laboratory teams maintain accurate and accessible records.
