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. Bio-Rad CFX96 Touch / CFX384 Interfacing Overview & Diagnostic Workflow
The Bio-Rad CFX96 Touch / CFX384 is an advanced diagnostic system utilizing real-time fluorescence thermocycling technology for hormones, tumor markers, cardiac biomarkers, infectious serology, and molecular pathogen detection. Integrating the Bio-Rad CFX96 Touch / CFX384 with AILS Cloud LIMS standardizes cut-off index (COI) calculations, calibrator curve tracking, and electronic batch signing.
AILS exports 96-well or 384-well plate setup layouts to the Bio-Rad CFX96 Touch / CFX384, linking sample accession IDs with internal positive/negative amplification controls.
Real-time cycle threshold (Ct) values and baseline-subtracted fluorescence metrics are ingested directly, automatically classifying qualitative pathogen detection (Detected / Not Detected / Indeterminate).

Sigmoidal baseline drift and non-specific amplification warnings are flagged in the verification console.
Frequently Asked Questions: Bio-Rad CFX96 Touch / CFX384 LIS 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.
