In GLP, the purpose of Standard Operating Procedures (SOPs) is to

• A. Describe study methods for ensuring the quality and integrity of data
• B. Provide training materials for staff
• C. Record all raw data automatically
• D. Calibrate equipment automatically

Answer: (A)

Standard Operating Procedures in GLP provide the exact methods for how studies are conducted, how samples are handled, how data are collected and recorded, and how analyses are performed. By detailing these steps, SOPs ensure consistency across personnel and studies, making results reliable, reproducible, and auditable. The emphasis is on guiding the study methods to protect data quality and integrity, not on automatically recording data or performing calibration. Training materials may be based on SOPs, but the core purpose of SOPs is to define the approved methods that safeguard data quality.
