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.

Bi-Directional Host Query & Rack Loading

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.

Serum Index & Auto-Dilution Reflux

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.

TECHNICAL FAQ

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.
