DNA Analysis Report Generator for Forensic Scientists
Create SWGDAM-compliant DNA analysis reports with statistical rigor and chain-of-custody document...
What You Can Do
This skill streamlines the creation of comprehensive DNA analysis reports that translate complex lab results into clear, legally defensible documentation. You can generate initial case reports, supplemental analyses for mixed profiles, CODIS hit documentation, and expert testimony frameworks while maintaining chain-of-custody integrity and calculating population statistics accurately according to current forensic best practices.
Features
automatically formats reports to meet Scientific Working Group on DNA Analysis Methods standards for admissibility
computes match probabilities, likelihood ratios, and population frequency data with appropriate databases
generates detailed tracking records for evidence handling from collection through analysis
provides structured guidance for analyzing multi-contributor profiles with clear reasoning and statistical support
creates statements and exhibits formatted for courtroom presentation and cross-examination preparation
documents positive/negative controls, validation results, and analytical thresholds met
formats database hit reports with appropriate disclaimers and investigative leads language
develops clear reasoning and recommendations when results don't support definitive inclusions or exclusions
Example Output
Example 1: Initial DNA Analysis Report
- Itemized evidence receipt with sample IDs and processing dates
- Analytical method summary (STR typing, next-gen sequencing)
- Peak height data and allele calls for loci analyzed
- Population statistics: "The probability of randomly selecting an unrelated individual with this DNA profile is 1 in 47.3 billion"
- Quality assurance sign-off confirming positive and negative control results
Example 2: Mixed Profile Supplemental Report
- Contributor number assessment with statistical support
- Peak height ratios and probabilistic genotyping results
- Statement: "Individual X cannot be excluded as a contributor to the mixture. The likelihood ratio is 2,450:1 in favor of inclusion."
- Mixture deconvolution methodology and assumptions documented
Example 3: Expert Testimony Framework
- Credentials and experience summary
- Case-specific CV highlighting relevant prior testimony
- Visual aids script (autosomal profile charts, population frequency graphs)
- Anticipated defense challenges with prepared responses
What's Included
- SKILL.md instruction file with full reporting protocol and SWGDAM compliance checklist:
- Initial Report Template: structured sections for evidence description, methodology, results, and conclusions
- Mixed Profile Analysis Worksheet: mixture deconvolution framework with statistical calculation guides
- Chain-of-Custody Checklist: granular tracking from collection through analysis completion
- Expert Testimony Framework: courtroom language templates and cross-examination preparation guide
- Quality Assurance Documentation: validation summary and control result logging
