58.35 Quality Assurance Unit
―A testing facility shall have a quality assurance unit which shall be responsible for monitoring each study to assure management that the facilities, equipment, personnel, methods, practices, records, and controls are in conformance with the regulations in this part. For any given study, the quality assurance unit shall be entirely separate from and independent of the personnel engaged in the direction and conduct of that study.‖

58.41 General
―Each testing facility shall be of suitable size and construction to facilitate the proper conduct of nonclinical laboratory studies. It shall be designed so that there is a degree of separation that will prevent any function or activity from having an adverse effect on the study.‖
绪言
药品非临床研究质量管理规范 (GLP)
The analytical laboratory conducting pharmacology/toxicology and other preclinical studies for regulatory submissions should adhere to FDA Good Laboratory Practices (GLPs) (21 CFR 58).

58.33 Study Director
―For each nonclinical laboratory study, a scientist or other professional of appropriate education, training, and experience, or combination thereof, shall be identified as the study director. The study director has overall responsibility for the technical conduct of the study, as well as for the interpretation, analysis, documentation, and reporting of results, and represents the single point of study control.‖
绪言
分析方法验证的种类—交叉验证
Comparison validation parameters of two bioanalytical methods Two or more bioanalytical methods for the same study or across
different studies : an original validated bioanalytical method and the revised bioanalytical method. Sample from a single study, but analysis at more than one site or more than one laboratory, cross-validation with spiked matrix standards and subject samples should be conducted at each site or laboratory to establish inter laboratory reliability. Data generated using different analytical techniques (e.g., LC-MSMS vs. ELISA) in different studies are included in a regulatory submission. All modifications should be assessed to determine the recommended degree of validation.
(b)―Each testing facility shall maintain a current summary of training and experience and job description for each individual engaged in or supervising the conduct of a nonclinical laboratory study.‖

分析方法验证的种类—部分验证
Partial validations are modifications of already validated bioanalytical methods.
Bioanalytical method transfers between laboratories or analysts Change in analytical methodology (e.g., change in detection systems) Change in anticoagulant in harvesting biological fluid Change in matrix within species (e.g., human plasma to human urine) Change in sample processing procedures Change in species within matrix (e.g., rat plasma to mouse plasma) Change in relevant concentration range Changes in instruments and/or software platforms Limited sample volume (e.g., pediatric study) Rare matrices Selectivity demonstration of an analyte in the presence of concomitant medications Selectivity demonstration of an analyte in the presence of specific metabolites
