Selectra Junior Bi-Directional LIS Interfacing Guide
Complete engineering specification, HL7/ASTM protocols, pinouts, and parameter mapping for Selectra Junior on AILS Cloud LIMS.
1. Instrument Overview & Interfacing Architecture
The Selectra Junior is a high-performance biochemistry 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.
2. Hardware Connection & Communication Settings
3. Sample Message Wire Frame
Below is a real-world communication frame transmitted between the Selectra Junior and AILS LIS middleware:
[SELECTRA_JUNIOR_STREAM] PATIENT_ID: ACC2026081520 NAME: Scott, Edward TEST: GLUCOSE = 92.0 mg/dL [Ref: 70-100] TEST: UREA = 24.5 mg/dL [Ref: 15-45] TEST: CREATININE = 0.90 mg/dL [Ref: 0.6-1.2] STATUS: OK
4. Parameter & LOINC Standard Code Mapping
| Instrument Code | LOINC Code | Clinical Parameter Name | Standard Units | Default Reference Range |
|---|---|---|---|---|
| GLU | 2345-7 | Glucose | mg/dL | 70.0 - 100.0 |
| UREA | 3094-0 | Urea | mg/dL | 15.0 - 45.0 |
| CREA | 2160-0 | Creatinine | mg/dL | 0.6 - 1.2 |
5. Biomedical Engineering Tips & Common Gotchas
In Selectra Junior setup menu, configure Serial Output to Continuous / Real-Time.
AILS Gateway captures raw text strings and parses key-value pairs automatically.
Use shielded serial cable to avoid electromagnetic noise in the laboratory.
Frequently Asked Questions: Selectra Junior Interfacing
Common biomedical engineering questions regarding connection, worklist setup, and data capture with AILS Cloud LIMS.
Q: How does Selectra Junior send test results to LIS?
Selectra Junior outputs structured ASCII text records over its RS-232 serial port upon test completion.
Q: What serial settings are required for Selectra Junior?
Baud Rate: 9600 bps; Data Bits: 8; Parity: None; Stop Bits: 1.
Q: Can Selectra Junior results be imported via CSV file watcher?
Yes. If an export utility saves runs to a local folder, AILS File Watcher can ingest the CSV files automatically.
Q: How does AILS handle calibration and blank readings on Selectra Junior?
Reagent blanks and calibration readings are logged in the QC audit trail without creating false patient reports.
Q: What cable pinout is needed for Selectra Junior DB9 connection?
A standard DB9 Null Modem Cable (Pin 2-Rx, Pin 3-Tx, Pin 5-GND).
