methodentransfer

Methodentransfer is the process of relocating an analytical, computational, or experimental method from a source laboratory or team to a receiving laboratory or team, with the goal of achieving equivalent performance and results. It is common in regulated environments such as pharmaceutical development, quality control, and contract research, but also occurs in software, data science, and manufacturing where consistent procedures are essential.

In analytical method transfer, the sending organization documents the method protocol, performance characteristics, equipment, and reagents. The receiving site implements the method and conducts transfer studies to compare results on representative samples or reference materials. Equivalence is demonstrated against pre-defined acceptance criteria for accuracy, precision, range, robustness, and, if relevant, detection limits. The transfer is typically governed by a formal plan and culminates in a transfer report that records evidence of comparability and any deviations.

Key elements include a detailed transfer plan, equipment qualification and calibration, personnel training, method suitability testing, and comprehensive documentation. Side-by-side analyses, matrix studies, and ruggedness testing are common components to assess method robustness across different conditions.

Common challenges involve differences in instruments, reagent lots, operator technique, and sample matrices. Effective risk mitigation relies on clear governance, thorough documentation, training, and adherence to applicable standards and regulatory requirements, such as ISO/IEC 17025, good laboratory practice, or corresponding industry guidelines. The expected outcome is a validated, approved method at the receiving site with ongoing monitoring and, if needed, requalification.
