Selectra ProS Bi-Directional LIS Interfacing Guide
Complete engineering specification, HL7/ASTM protocols, pinouts, and parameter mapping for Selectra ProS on AILS Cloud LIMS.
1. Selectra ProS Interfacing Overview & Diagnostic Workflow
The Selectra ProS is a high-performance clinical chemistry analyzer dedicated to routine photometric assays, enzymatic kinetics, and ion-selective electrode (ISE) electrolytes. Connecting the Selectra ProS 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.
As sample tubes enter the Selectra ProS reaction carousels, the onboard barcode reader queries AILS Gateway via ASTM E1381 / E1394 to pull ordered test profiles (e.g. Liver Function, Renal Panel, Lipid Profile) in under 300ms.
AILS automatically reads HIL (Hemolysis, Icterus, Lipemia) interferent flags emitted by the Selectra ProS, warning technologists when sample integrity compromises photometric accuracy and logging auto-dilution rerun factors.

Ensure AILS Gateway is configured with matching STX/ETX framing.
Frequently Asked Questions: Selectra ProS LIS Interfacing
Common biomedical engineering questions regarding connection, worklist setup, and data capture with AILS Cloud LIMS.
Q: What interface protocols are supported by Selectra ProS?
Selectra ProS supports ASTM E1381/E1394 over TCP/IP socket (Port 5002) and RS-232 serial.
Q: How does Selectra ProS transmit biochemistry test batches?
Results are transmitted in real time as ASTM record frames as each photometric reading completes.
Q: Can Selectra ProS operate with bi-directional worklists?
Yes. Sample barcodes scanned on the rotor are queried against AILS LIMS to fetch test profiles.
Q: How are ISE module parameters mapped on Selectra ProS?
Sodium, Potassium, and Chloride values are mapped to dedicated LOINC codes in AILS LIMS.
Q: What baud rate is used for Selectra ProS serial connections?
Standard baud rate is 9600 bps, 8 data bits, no parity, 1 stop bit.
