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. Sysmex XT-2000i Interfacing Overview & Diagnostic Workflow
The Sysmex XT-2000i 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 Sysmex XT-2000i 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 coordinates with the Sysmex XT-2000i auto-sampler and barcode scanner, dispatching ASTM order records mapped to patient accession IDs to queue 3-part or 5-part differential testing.
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.

5. Sysmex Biomedical Engineering Field Notes & 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 LIS 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.
