Q 8. How do you handle deviations from GLP procedures?
Deviations from GLP procedures are inevitable, but how we handle them is crucial. A deviation is any unplanned event that differs from the approved SOP (Standard Operating Procedure). The first step is immediate documentation. This involves clearly describing the deviation, the time it occurred, the individuals involved, and the actions taken to mitigate its impact. We then assess the severity of the deviation. A minor deviation might require a simple written explanation and corrective action. For example, if a reagent was inadvertently used slightly past its expiration date (within a reasonable timeframe and deemed stable), the details would be recorded in a deviation log, and the data impacted would be evaluated for potential issues. However, a major deviation, such as a significant equipment malfunction affecting a large dataset, demands a much more thorough investigation, potentially involving a root cause analysis. This process aims to identify the underlying cause of the deviation and to implement preventive measures to stop recurrence. It might involve revisiting the SOP, retraining personnel, or upgrading equipment. All deviations, regardless of severity, are reported to the study director and documented within the study’s raw data. Ultimately, transparency and thorough documentation are key to maintaining data integrity and GLP compliance.
Q 9. Explain your understanding of Standard Operating Procedures (SOPs).
Standard Operating Procedures (SOPs) are the backbone of GLP. They are detailed, written instructions that standardize laboratory processes, ensuring consistency and reproducibility of results. Think of them as recipe books for experiments. A well-written SOP includes clear step-by-step instructions, safety precautions, quality control checks, and acceptance criteria.

Q 16. Explain your understanding of raw data vs. processed data.
In GLP, understanding the distinction between raw data and processed data is crucial. Raw data represents the initial, uninterpreted measurements or observations collected directly from experiments. Processed data, on the other hand, is derived from the raw data after various transformations, calculations, or analyses.
Raw data is the foundation. Imagine it as the ingredients for a cake – the flour, sugar, eggs, etc. It is the primary source of information and should be preserved in its original form. Examples include instrument readings, chromatograms, lab notebooks, etc. It’s imperative that all raw data are properly documented and maintained, unchanged and readily accessible.
Processed data is the result of manipulating or interpreting the raw data. This is like the baked cake – the final product. It’s vital to meticulously document all processing steps to ensure traceability and reproducibility. Examples include calculated concentrations, statistical summaries, and graphs. These results are derived from the original data and must be justified and supported.
A simple example: If you measure the weight of a sample on a balance (raw data: 10.25 grams), and then calculate the concentration based on that weight (processed data: 5.125 mg/mL), you must keep the original weight measurement accessible and clearly link it to the calculated concentration. Failure to do this compromises data traceability and integrity.
Q 17. What are the key elements of a GLP-compliant laboratory environment?
A GLP-compliant laboratory environment needs several key elements to ensure data quality and reliability. These can be broadly categorized as personnel, facilities, equipment, and documentation.
