Under GLP, which item can be considered raw data?

• A. A voice recording
• B. A photo
• C. A handwritten data entry
• D. All of the above

Answer: (D)

Raw data are the original records that capture observations and measurements exactly as they were collected during the study. In GLP, these records must be true, unaltered, and traceable so the study can be reconstructed and audited. A voice recording can be raw data because it preserves the exact sounds and statements made at the time of the experiment. A photo can be raw data if it’s the original image taken to document a condition or result, without modification. A handwritten data entry can also be raw data if it’s the initial note or measurement recorded by the researcher before any processing. Since each form can serve as an original, unprocessed record, all of the items listed are examples of raw data. Hence, the best answer is that all of the above can be raw data, provided they are preserved in their original, unaltered state and properly documented for traceability.
