UF PHA 6936 Forensic Science Mock Final Exam
2026 | Trusted Questions & Answers
1. Describe how matrix-matched calibration standards contribute to the
accuracy of forensic analysis.
Matrix-matched calibration standards are used to reduce the time
needed for analysis.
Matrix-matched calibration standards are irrelevant to the accuracy of
forensic analysis.
Matrix-matched calibration standards only apply to chemical analysis,
not biological samples.
Matrix-matched calibration standards help to account for the effects
of the sample matrix on the measurement, thus improving accuracy.
2. Describe the importance of maintaining a chain of custody when collecting
urine samples for forensic analysis.
Maintaining a chain of custody only applies to samples collected in a
laboratory setting.
Maintaining a chain of custody is only necessary for blood samples,
not urine.
Maintaining a chain of custody ensures that the sample remains
uncontaminated and its integrity is preserved throughout the
analysis process.
Maintaining a chain of custody is irrelevant as long as the sample is
collected properly.
3. If a forensic laboratory discovers that their equipment has not been properly
calibrated, what immediate action should they take to ensure data integrity?
Replace the equipment entirely.
, Recalibrate the equipment and document the process.
Continue using the equipment without changes.
Ignore the issue if no errors have been reported.
4. Provide information about the work done in the laboratory: raw data,
instrument repair, modules, drafts, publications. It also provides financial and
legal protection for the laboratory and individuals.
Non-records
Records
Personal papers
All of the above
5. If a laboratory fails to calibrate its pipettes regularly, what potential impact
could this have on forensic analysis results?
It would only affect the cost of the analysis.
It would have no impact on the analysis results.
It could lead to inaccurate measurements and compromised data
integrity.
It would improve the efficiency of the laboratory processes.
6. Describe the significance of the merger between LAB and ASCLAD in the
context of forensic science accreditation.
The merger had no significant impact on forensic science
accreditation.
The merger focused on increasing the number of forensic
laboratories.
, The merger was intended to reduce the number of accreditation
bodies.
The merger aimed to enhance the quality assurance and
accreditation processes in forensic science.
7. Describe the significance of variance in the context of quality assurance in
forensic science.
Variance is irrelevant in quality assurance and has no impact on data
accuracy.
Variance only applies to qualitative data and is not used in forensic
science.
Variance is a method for collecting samples in forensic investigations.
Variance is important in quality assurance as it measures the
dispersion of data, indicating the precision of measurements.
8. What is the primary reason for separating samples during transit, storage, and
analysis?
To reduce costs
To simplify documentation
To enhance data analysis
To prevent contamination
9. What is the purpose of using matrix-matched calibration standards in forensic
science?
To ensure that the calibration standards closely resemble the
sample matrix.
To eliminate the need for sample collection.
, To provide a universal standard for all types of samples.
To simplify the calibration process by using a single standard.
10. If a forensic laboratory fails to consider the relevance of analytes in its
analytical suite, what potential consequence could arise for the customer?
The customer may receive irrelevant or unhelpful results.
The laboratory will save time and resources.
The results will always be accurate regardless of analyte choice.
The laboratory will enhance its reputation for quality.
11. What is one of the primary responsibilities of personnel involved in a QA/QC
program in forensic science?
To analyze data without following protocols
To use maintained and calibrated equipment
To disregard contamination concerns
To collect samples without any documentation
12. If a forensic laboratory fails to maintain accurate personnel files regarding
qualifications and training, what potential impact could this have on the
laboratory's QA/QC program?
It would have no impact on the laboratory's operations.
It could compromise the integrity of the laboratory's results and
overall quality assurance.
It would only affect employee morale.
It could lead to increased funding for the laboratory.
