BT3000 Plus / Chameleon Bi-Directional LIS Interfacing Guide
Complete engineering specification, HL7/ASTM protocols, pinouts, and parameter mapping for BT3000 Plus / Chameleon on AILS Cloud LIMS.
1. BT3000 Plus / Chameleon Interfacing Overview & Diagnostic Workflow
The BT3000 Plus / Chameleon is a high-performance clinical chemistry analyzer dedicated to routine photometric assays, enzymatic kinetics, and ion-selective electrode (ISE) electrolytes. Connecting the BT3000 Plus / Chameleon 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.
Photometric absorbance calculations and ISE potential readings transmitted by the BT3000 Plus / Chameleon are ingested in real time, converting raw analyzer voltage/OD readings into calibrated clinical concentrations.
AILS automatically reads HIL (Hemolysis, Icterus, Lipemia) interferent flags emitted by the BT3000 Plus / Chameleon, warning technologists when sample integrity compromises photometric accuracy and logging auto-dilution rerun factors.
