Sysmex XT-2000i Bi-Directional LIS Interfacing Guide
Complete engineering specification, HL7/ASTM protocols, pinouts, and parameter mapping for Sysmex XT-2000i on AILS Cloud LIMS.
1. Instrument Overview & Interfacing Architecture
The Sysmex XT-2000i 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.

| Instrument Code | LOINC Code | Clinical Parameter Name | Standard Units | Default Reference Range |
|---|---|---|---|---|
| WBC | 6690-2 | White Blood Count | 10*3/uL | 4.0 - 11.0 |
| RET% | 17849-1 | Reticulocyte Percentage | % | 0.5 - 2.0 |
| RET# | 787-2 | Reticulocyte Absolute | 10*6/uL | 0.02 - 0.10 |
| IRF | 33256-9 | Immature Reticulocyte Fraction | Ratio | 0.1 - 0.3 |
5. Biomedical Engineering Tips & Common Gotchas
Ensure the fluorescent optical bench reticulocyte channel is enabled in analyzer transmission settings.
Verify that sample rack barcode reader reads both Codabar and Code 128 formats.
AILS Gateway decodes extended platelet indices (P-LCR, MPV, PDW) automatically.
Frequently Asked Questions: Sysmex XT-2000i Interfacing
Common biomedical engineering questions regarding connection, worklist setup, and data capture with AILS Cloud LIMS.
Q: What protocol does Sysmex XT-2000i use for data transmission?
Sysmex XT-2000i uses ASTM E1394 standard protocol over TCP/IP socket (Port 5001) or RS-232 serial communication.
Q: How are optical reticulocyte parameters mapped in AILS?
Parameters including RET#, RET%, IRF (Immature Reticulocyte Fraction), and LFR/MFR/HFR are parsed into dedicated LOINC coded fields.
Q: Can XT-2000i connect in bi-directional mode?
Yes. When connected via TCP/IP to AILS Gateway, the analyzer queries the host upon reading sample barcodes and receives test panel instructions.
Q: How does AILS handle flagging on Sysmex XT-2000i?
Abnormal WBC scattergram flags, RBC agglutination warnings, and platelet clump flags are recorded in the accession audit log.
Q: What is the recommended network setup for Sysmex XT-2000i?
Assign a static IP address to the Sysmex IPU PC and set AILS Gateway to listen on TCP Port 5001 as Server.
