Sample interview questions: How do you ensure accuracy and precision in your forensic analyses?
Sample answer:
Accuracy and Precision in Forensic Analyses
Ensuring Accuracy
- Calibration and Verification: Regularly calibrate instruments using certified standards to ensure accuracy and minimize systematic errors.
- Blanks and Controls: Include proper blanks and controls in all analyses to account for potential contamination or background signals.
- Method Validation: Validate analytical methods before implementation to establish their performance characteristics, including specificity, sensitivity, and accuracy.
- Proficiency Testing: Participate in external proficiency testing programs to compare results with other laboratories and identify any potential biases.
Ensuring Precision
- Replicate Analyses: Perform multiple replicate analyses on all samples to assess precision and minimize random errors.
- Sample Preparation Consistency: Standardize sample preparation procedures and use controlled conditions to ensure consistent results.
- Analytical Robustness: Optimize analytic… Read full answer
