Introduction
Home > STR Data Analysis & Interpretation > Data Interpretation & Allele Calls > Introduction
The interpretation of results in casework can be one of the most difficult aspects of forensic DNA analysis and is a matter of professional judgment and expertise.01 It is not possible or practical to develop interpretation criteria that cover every circumstance. Laboratories should develop interpretation guidelines that are based on validation studies, literature, methodology, and experience. It is expected that laboratory guidelines will evolve as the collective experience of the laboratory and the forensic science community grows. Interpretation guidelines provide a framework for the objective and consistent interpretations of results.
Objectives
Upon successful completion of this unit of instruction, the student shall be able to:
- Describe the factors that can influence the output from instruments used in DNA analysis
- Describe controls and other techniques used to validate instrument output
- Compare methods used to evaluate data and recognize analysis artifacts
- Explain methods used to analyze data from single source and mixed source samples
