Horiba Yumizen H500 / H550 Bi-Directional LIS Interfacing Guide
Complete engineering specification, HL7/ASTM protocols, pinouts, and parameter mapping for Horiba Yumizen H500 / H550 on AILS Cloud LIMS.
1. Instrument Overview & Interfacing Architecture
The Horiba Yumizen H500 / H550 is a high-performance hematology instrument designed for diagnostic laboratories and hospital health networks. Integrating this analyzer directly with AILS Cloud LIMS eliminates manual transcription delays, prevents typographical patient identification errors, and automatically enforces Westgard delta check algorithms.
AILS automatically generates worklist queries (QRY^Q02 / ASTM orders) mapped to patient accession barcodes and pushes test instructions directly to the instrument sample tray.
Raw OBX / Result records are parsed instantly within 200 milliseconds, flagged for abnormal reference ranges, and linked to pathologist digital signature queues.

5. Biomedical Engineering Tips & Common Gotchas
In Yumizen H500 menu, select LIS Protocol as HL7 and enter Gateway IP and Port 5001.
AILS Gateway returns ACK^R01 confirmation to complete the transmission handshake.
Check micro-volume tube adapter mode settings if analyzing pediatric tubes.
Frequently Asked Questions: Horiba Yumizen H500 / H550 Interfacing
Common biomedical engineering questions regarding connection, worklist setup, and data capture with AILS Cloud LIMS.
Q: What communication standard is used by Horiba Yumizen H500?
Horiba Yumizen H500 uses HL7 v2.3.1 over TCP/IP MLLP socket.
Q: Does Yumizen H500 support bi-directional worklists?
Yes. Sample tube barcodes are queried against AILS LIMS and test profiles are downloaded automatically.
Q: How are 5-part differential parameters mapped in AILS?
Full 5-part differentials (NEU, LYM, MON, EOS, BAS) in absolute and relative percentages are mapped to LOINC codes.
Q: What throughput is supported on Yumizen H500?
Yumizen H500 processes up to 60 samples per hour in full 5-part differential mode.
Q: Are Yumizen abnormal cell morphology flags recorded?
Yes. Pathology warnings such as Immature Granulocytes and Blast flags are displayed in the review console.
