Hematology Workflow

Pre-Analytical Sample Sorting

The Challenge

A mixture of EDTA and citrate samples are received into the hematology department and need to be pre-sorted and loaded into analyzer racks for testing. Staff must scan each sample into the LIS to confirm test requests and manually sort tubes into different analyzer racks:

  • CBC samples → Hematology analyzer rack
  • HbA1c samples → Chemistry analyzer rack
  • Coagulation samples → Coagulation analyzer rack

Post-Analytical Sample Processing

The Challenge

This laboratory processes approximately 5,000 complete blood counts (CBC) per day. After completion of CBC testing, all samples must be manually scanned into the LIS where staff check for test completion, review results to determine if a blood film is required, identify additional test requests (such as ESR and HbA1c), and sort samples for subsequent testing. This process repeats until all test requests are completed, followed by manual scanning to assign storage locations.

This workflow requires 2 full-time employees over multiple shifts. The laboratory experiences delayed result reporting when errors occur.

Assign Storage

PathFinder Solution

After samples are processed on the hematology analyzer, analyzer racks are loaded directly onto the PathFinder 450S. The system scans sample barcodes, queries the LIS for CBC results and outstanding test requests, and automatically sorts samples to appropriate destination racks. Samples are presented to the PathFinder multiple times for recursive sorting until all requests are complete. Storage locations are exported directly into the LIS for sample traceability.

Key Benefits of Automating Hematology Workflows

  • Automated sorting eliminates manual scanning and sorting tasks
  • LIS integration automatically determines test requirements
  • Samples sorted directly into analyzer-specific racks
  • Error reduction through elimination of manual sort decisions
  • Staff reduction/re-allocation of 2 full-time employees through automation
  • Improved test completion rates due to error reduction
  • Recursive sorting automatically handles multi-stage testing workflows
