URIT 5250 Bi-Directional LIS Interfacing Guide
Complete engineering specification, HL7/ASTM protocols, pinouts, and parameter mapping for URIT 5250 on AILS Cloud LIMS.
1. URIT 5250 Interfacing Overview & Diagnostic Workflow
The URIT 5250 is an automated hematology platform engineered for high-precision complete blood counts (CBC) and white blood cell differential analysis. In modern clinical laboratory workflows, interfacing the URIT 5250 directly to AILS Cloud LIMS eliminates manual transcription delays, captures full WBC scattergram channel flags (such as immature granulocytes, atypical lymphocytes, and platelet clumps), and validates patient results against historical delta check baselines in real time.
AILS Gateway parses sample accession barcodes from the URIT 5250 data stream, linking multi-parameter CBC results directly to open patient encounter records without manual intervention.
Raw result segments are evaluated instantly against laboratory reference intervals and Westgard multirule delta check algorithms. Critical alerts (e.g. severe thrombocytopenia or extreme leukocytosis) trigger automatic hold flags for pathologist microscopic smear review.

Frequently Asked Questions: URIT 5250 LIS Interfacing
Common biomedical engineering questions regarding connection, worklist setup, and data capture with AILS Cloud LIMS.
Q: What communication protocol does URIT 5250 use?
URIT 5250 uses HL7 v2.3.1 over TCP/IP MLLP socket.
Q: How does AILS Gateway process 5-part differential results from URIT 5250?
Full 5-part differential parameters (NEU, LYM, MONO, EOS, BASO) are extracted from OBX segments and mapped to LOINC codes.
Q: What network configuration is required for URIT 5250?
Connect via Cat6 Ethernet cable and set AILS Gateway to listen on TCP Port 5001.
Q: Does URIT 5250 support bi-directional worklists?
Yes. Sample tube barcodes are queried against AILS LIMS and test profiles are downloaded automatically.
Q: How are abnormal cell warnings handled on URIT 5250?
Flags such as Immature Granulocytes and Blast alerts trigger automatic pathologist review holds.
