One of the most important points for GLP studies is: A full description of what comprises raw data that is collected while following protocol instructions.

• A. A list of facilities
• B. A full description of what comprises raw data that is collected while following protocol instructions
• C. The study budget
• D. The final summary

Answer: (B)

In GLP, data integrity and traceability are central. A full description of what comprises raw data collected while following protocol instructions ensures that every original measurement, observation, instrument readout, and calculation is clearly defined, recorded, and preserved as it happened. This makes the data auditable, reproducible, and verifiable, and it supports regulatory review and the ability to reconstruct the study if needed. It also aligns with ALCOA principles—data should be attributable, legible, contemporaneous, original, and accurate—so documenting exactly what counts as raw data anchors trust in the results. Other aspects like listing facilities, the study budget, or the final summary don’t establish how raw data are captured or retained, so they don’t address this key GLP requirement.
