Method Validation Seminar June 06 © 2006 LGC Limited 4 Method performance parameters Providing evidence that the method produces results that are fit-for-purpose Wayne, Pennsylvania, USA—The Clinical and Laboratory Standards Institute has published Validation and Verification of Multiplex Nucleic Acid Assays —MM17. Food and Drug Administration. Analyse-it has helped tremendously. CLSI C62-A, 2014. Using statistics to determine accuracy, a method validation can establish the instrument performance compared to a gold standard method. The validation of a qualitative method requires much lesser effort, than the validation of a quantitative method. Laboratory validation of a clinical metagenomic sequencing assay for pathogen detection in cerebrospinal fluid Steve Miller,1,2,10 Samia N.

It is unsurpassed in its class, especially in terms of ease-of-use, which makes it suitable and highly recommended for every-day-use. Methods: Analytical precision was measured by testing five breast tumor RNA samples across 3 sites. In 2003 his specialist degree was accepted by the Royal College of Pathologists in London and he was admitted to the Specialist Register of the General Medical Council. • Clinical significance - leads to accurate medical decisions • Required by CLIA*, CAP, and The Joint Commission (*Clinical Laboratory Improvements Amendments of 1988) • Pass proficiency testing • Improvements over existing methodology • Assay validation requirements vary: Non-FDA approved > FDA approved > Waived tests The validation procedure was based on several Clinical and Laboratory Standards Institute (CLSI) protocols, with the details given below in the Materials and Methods section.
