Bio-Rad CFX96 Touch / CFX384 Bi-Directional LIS Interfacing Guide
Complete engineering specification, HL7/ASTM protocols, pinouts, and parameter mapping for Bio-Rad CFX96 Touch / CFX384 on AILS Cloud LIMS.
1. Instrument Overview & Interfacing Architecture
The Bio-Rad CFX96 Touch / CFX384 is a high-performance molecular pcr 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 Bio-Rad CFX Manager / CFX Maestro, enable 'Automated Export on Run Completion' to the LIS watched directory.
AILS Gateway directory monitor detects and parses new plate CSV files within 500ms.
Sigmoidal baseline drift and non-specific amplification warnings are flagged in the verification console.
Frequently Asked Questions: Bio-Rad CFX96 Touch / CFX384 Interfacing
Common biomedical engineering questions regarding connection, worklist setup, and data capture with AILS Cloud LIMS.
Q: How does AILS LIMS integrate with Bio-Rad CFX96 and CFX384 PCR systems?
AILS File Watcher monitors the designated network export directory where CFX Maestro software automatically saves completed run spreadsheets (CSV/XML), instantly parsing well assignments and Ct calls.
Q: How are multiplex optical channels (FAM, HEX/VIC, Texas Red/ROX, Cy5) distinguished?
AILS parses the fluorophore and target columns in the exported CSV, matching each optical channel to its corresponding clinical parameter in the molecular test battery.
Q: Does AILS support 96-well and 384-well plate map creation?
Yes. AILS Molecular Module generates plate setup files (.pltd) with sample accession numbers, positive controls, and negative controls for direct import into CFX Maestro.
Q: How does AILS validate positive and negative run controls?
AILS checks that Negative Controls (NTC) show N/A Ct and Positive Controls fall within expected Ct ranges before validating patient results on the plate.
Q: Can raw amplification curve images be linked to patient electronic reports?
Yes. High-resolution multi-channel amplification plot images generated by CFX Maestro can be automatically attached to patient digital PDF reports.
