Roche Cobas c501 / c502 / Integra 400 Bi-Directional LIS Interfacing Guide
Complete engineering specification, HL7/ASTM protocols, pinouts, and parameter mapping for Roche Cobas c501 / c502 / Integra 400 on AILS Cloud LIMS.
1. Instrument Overview & Interfacing Architecture
The Roche Cobas c501 / c502 / Integra 400 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.

5. Biomedical Engineering Tips & Common Gotchas
In Cobas Core software, configure Host Protocol to ASTM E1394 Mode 2 for bi-directional query.
Ensure rack barcode format matches the identification string configured in AILS LIMS.
Check that reagent cassette lot numbers are synchronized with QC validation tables.
Frequently Asked Questions: Roche Cobas c501 / c502 / Integra 400 Interfacing
Common biomedical engineering questions regarding connection, worklist setup, and data capture with AILS Cloud LIMS.
Q: What interface standard is used by Roche Cobas c501 and cobas 6000 systems?
Roche Cobas systems utilize the Roche Host Interface (ASTM E1381/E1394) or HL7 v2.5 over TCP/IP socket (Port 6000) or RS-232 serial.
Q: How does Cobas c501 handle bi-directional sample worklist queries?
When a sample rack enters the loading line, the barcode reader sends a Q query. AILS Gateway responds with an O (Order) record containing requested test profiles.
Q: Can Cobas c501 chemistry and e601 immunoassay modules share one LIS connection?
Yes. Consolidated Cobas 6000 and 8000 core lab tracks connect via a single consolidated gateway interface.
Q: How are serum indices (Lipemia, Hemolysis, Icterus) handled in AILS?
Roche Serum Indices transmitted in comment or result records are linked to sample integrity flags in AILS LIMS.
Q: How are rerun and reflex tests scheduled on Cobas c501?
If a test result is out of linearity, AILS reflex rules can automatically command the Cobas to schedule an auto-diluted rerun.
