Diagnostica Stago STA Compact Max Bi-Directional LIS Interfacing Guide
Complete engineering specification, HL7/ASTM protocols, pinouts, and parameter mapping for Diagnostica Stago STA Compact Max on AILS Cloud LIMS.
1. Instrument Overview & Interfacing Architecture
The Diagnostica Stago STA Compact Max is a high-performance coagulation 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.

| FIB | 3255-7 | Fibrinogen Concentration | mg/dL | 200.0 - 400.0 |
5. Biomedical Engineering Tips & Common Gotchas
In Stago operating software, configure Host Transmission to ASTM E1394 standard format.
Mechanical clot detection is unaffected by lipemic, icteric, or hemolyzed samples.
Check French test code mappings (e.g. TP for PT, TCA for APTT) in the AILS dictionary.
Frequently Asked Questions: Diagnostica Stago STA Compact Max Interfacing
Common biomedical engineering questions regarding connection, worklist setup, and data capture with AILS Cloud LIMS.
Q: What communication protocol is used by Diagnostica Stago STA Compact?
Diagnostica Stago STA Compact and STA R Max use ASTM E1381/E1394 standard protocol over RS-232 serial or network data link.
Q: Why is Stago mechanical clot detection unique for LIS integration?
Stago's viscosity-based mechanical clot detection uses an oscillating magnetic steel ball, ensuring reliable clotting times even in severely lipemic or hemolyzed plasma without optical interference flags.
Q: How does AILS handle French test abbreviations from Stago analyzers?
AILS includes built-in cross-reference aliases mapping Stago French parameter codes (TP, TCA, TT) to international LOINC standards (PT, APTT, Thrombin Time).
Q: Does Stago STA Compact support bi-directional barcode worklists?
Yes. In bi-directional mode, Stago queries sample tube barcodes and downloads assigned hemostasis profiles.
Q: What serial cable is required for Stago STA Compact?
A standard DB9 Female Null Modem serial cable (Pins 2-3, 3-2, 5-5) at 9600 baud, 8 data bits, Parity None, 1 stop bit.
