Mindray BS-240 Bi-Directional LIS Interfacing Guide
Complete engineering specification, HL7/ASTM protocols, pinouts, and parameter mapping for Mindray BS-240 on AILS Cloud LIMS.
1. Mindray BS-240 Interfacing Overview & Diagnostic Workflow
The Mindray BS-240 is a high-performance clinical chemistry analyzer dedicated to routine photometric assays, enzymatic kinetics, and ion-selective electrode (ISE) electrolytes. Connecting the Mindray BS-240 to AILS Cloud LIMS establishes a closed-loop analytical cycle—automating test profile assignment, monitoring serum index flags (Hemolysis, Icterus, Lipemia), and preventing reporting errors across high-volume chemistry workloads.
As sample tubes enter the Mindray BS-240 reaction carousels, the onboard barcode reader queries AILS Gateway via HL7 v2.3.1 / HL7 v2.5.1 to pull ordered test profiles (e.g. Liver Function, Renal Panel, Lipid Profile) in under 300ms.
AILS automatically reads HIL (Hemolysis, Icterus, Lipemia) interferent flags emitted by the Mindray BS-240, warning technologists when sample integrity compromises photometric accuracy and logging auto-dilution rerun factors.
2. Mindray BS-240 TCP/IP Socket & Network Configuration
Standard RJ-45 Cat6 Ethernet TCP/IP Network Connection. Mindray LIS Server Port: 5001. Static IP configuration recommended.

Frequently Asked Questions: Mindray BS-240 LIS Interfacing
Common biomedical engineering questions regarding connection, worklist setup, and data capture with AILS Cloud LIMS.
Q: What interface standard does Mindray BS-240 use?
Mindray BS-240 uses HL7 v2.3.1 or HL7 v2.5 over TCP/IP MLLP socket (Port 5001).
Q: Does Mindray BS-240 support bi-directional sample queries?
Yes. When a tube barcode is read on the sample carousel, BS-240 queries AILS LIMS and downloads the requested chemistry panel.
Q: How are biochemistry panel test codes mapped?
Short test codes (e.g. GLU, CREA, SGPT, SGOT, BIL-T, UREA) are mapped to standard LOINC codes in AILS LIMS.
Q: How are auto-dilution results processed from BS-240?
If an analyte concentration exceeds the linearity range, BS-240 applies automated dilution and transmits the multiplied result with flag D.
Q: Can Mindray BS-240 calibration and QC data be tracked?
Yes. QC results are routed to AILS Levey-Jennings quality management module automatically.
