LC-MS/MS SOFTWARE DATA PROCESSING AND REVIEW WORKFLOW IMPROVEMENTS FOR CLINICAL RESEARCH

Significance of the Topic

The increasing demand for high-throughput, accurate and compliant quantitative LC-MS/MS data analysis in clinical research has driven the development of advanced software tools. Efficient review workflows ensure adherence to regulatory guidelines, reduce manual errors and accelerate decision-making in bioanalytical laboratories.

Objectives and Study Overview

This study assesses improvements in data processing and review workflow achieved by the new waters_connect QUAN Review software, compared with the established TargetLynx IVD Application Manager. By evaluating precision, bias and review efficiency across three multiplexed immunosuppressant panels, the authors demonstrate how optimized software features can enhance clinical LC-MS/MS operations.

Methodology and Instrumentation

Samples representing three validated multiplexed panels were acquired on Waters IVD LC-MS/MS systems controlled by MassLynx IVD software. Raw data were imported into waters_connect via the Explorer module, then processed and reviewed with both QUAN Review and TargetLynx IVD. Method performance criteria followed FDA Bioanalytical Method Validation and CLSI C62-Ed2 guidelines.

Instrumentation

• Waters IVD LC-MS/MS systems
• MassLynx IVD Software
• waters_connect for IVD Hub (Explorer, QUAN Review, Administration modules)
• TargetLynx IVD Application Manager

Main Results and Discussion

Precision and bias metrics were equivalent between QUAN Review and TargetLynx IVD. Repeatability and total precision for cyclosporine, everolimus, sirolimus and tacrolimus showed comparable %CV values (e.g., cyclosporine repeatability 2.2% and total precision 5.9% for both tools). Mean bias on external quality assurance samples also aligned closely. The exception-focused review reduced manual inspection time by up to 50%, while batch-level and task-oriented workflows simplified complex data handling.

Benefits and Practical Applications

• Immediate batch pass/fail overview
• Review-by-exception rule sets
• Trend monitoring of internal standards and retention time
• Task-oriented, decoupled review steps
• Efficient multi-chromatogram assessment

Future Trends and Applications

Ongoing enhancements may include AI-driven anomaly detection, cloud-based collaboration, deeper integration with laboratory information systems and expanded support for emerging biomarkers. Such developments will further streamline LC-MS/MS workflows and improve data integrity.

Conclusion

The waters_connect QUAN Review software delivers equivalent analytical performance to the established TargetLynx IVD tool while significantly reducing review time and simplifying complex workflows. Its exception-focused and task-oriented design supports regulatory compliance and enhances laboratory productivity.
