In GLP data integrity, does the format of raw data matter in determining whether it is raw data?

• A. No, both can be raw data
• B. Yes, only written notes are raw data
• C. Yes, only photos are raw data
• D. Yes, only voice recordings are raw data

Answer: (A)

The main idea here is that raw data in GLP is defined by being the original record of an observation or measurement, not by the format it’s in. In GLP, raw data can come in many forms—handwritten notes, instrument printouts, photographs, audio, or video recordings—as long as they faithfully capture the original result and can be traced back to the study. So the format does not determine whether something is raw data; its authenticity, completeness, and ability to reconstruct the result are what matter. Therefore, both written notes and photos can be raw data under GLP, depending on whether they represent the original observation and are preserved properly. The other choices are too restrictive, implying only one type of format can be raw data, which isn’t consistent with GLP data integrity principles.
