Bruker MALDI Biotyper sirius / microflex Bi-Directional LIS Interfacing Guide
Complete engineering specification, HL7/ASTM protocols, pinouts, and parameter mapping for Bruker MALDI Biotyper sirius / microflex on AILS Cloud LIMS.
1. Instrument Overview & Interfacing Architecture
The Bruker MALDI Biotyper sirius / microflex is a high-performance microbiology 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 Bruker MALDI Biotyper Compass software, configure Auto-Export of identification runs to CSV/XML format.
AILS Gateway parses 96-spot target plate files within 500ms of spectral database matching.
Log scores >= 2.00 are classified as Green (Highly Probable Species Identification) and queued for pathologist verification.
Frequently Asked Questions: Bruker MALDI Biotyper sirius / microflex Interfacing
Common biomedical engineering questions regarding connection, worklist setup, and data capture with AILS Cloud LIMS.
Q: How does AILS LIMS integrate with Bruker MALDI Biotyper systems?
AILS File Watcher monitors the designated export directory where Bruker Compass software automatically outputs completed run reports, parsing target spot coordinates, organism species, and log-scores.
Q: How are Bruker MALDI Biotyper Log-Scores classified in AILS?
Log scores are categorized per clinical guidelines: 2.00 - 3.00 (High-Confidence Species Level ID), 1.70 - 1.99 (Probable Genus Level ID), and < 1.70 (Not Reliable ID / Requires Rerun).
Q: Does AILS support 96-spot and 48-spot target plate setup?
Yes. AILS generates complete MALDI target plate map files with sample IDs and matrix control spots (BTS) for 1-click import into flexControl.
Q: How does MALDI-TOF identification accelerate blood culture turnaround?
When a blood culture bottle turns positive, direct rapid MALDI extraction identifies the causative pathogen within 15 minutes, cutting over 24 hours off traditional subculture workflows.
Q: Can mass spectra profiles and top 10 matching candidate organisms be viewed in AILS?
Yes. The top database matches, spectral peak comparisons, and NCBI Taxonomy IDs are stored in the patient's microbiology case file.
