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. Diagnostica Stago STA Compact Max Interfacing Overview & Diagnostic Workflow
The Diagnostica Stago STA Compact Max is a precision diagnostic analyzer designed for clinical laboratory testing. Connecting the Diagnostica Stago STA Compact Max directly to AILS Cloud LIMS eliminates manual data entry, prevents typographical identification errors, and delivers verified results directly to ordering physicians and hospital EMRs.
AILS Gateway manages bi-directional ASTM E1394 / Serial Data Link worklist handshakes with the Diagnostica Stago STA Compact Max, streaming patient test requests as samples are loaded.
Results are checked against age- and gender-adjusted reference ranges, delta check baselines, and quality control (QC) Levey-Jennings rules before digital sign-off.

5. Diagnostica Stago Biomedical Engineering Field Notes & 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 LIS 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.
