Three SNP options in a full technology suite for optimal results
There are three main ways to perform SNP analysis for Forensic Investigative Genetic Genealogy (FIGG): Whole Genome Sequencing (WGS), targeted sequencing with the ForenSeq Kintelligence kit, and SNP array. Which method is used should be determined by the evidence, not limited by the capabilities of the lab. DNA Labs International is the only laboratory to have all three technologies in-house plus SNP triage™, a proprietary method of sample triage, as part of our genealogy solution.
We follow ANAB and ISO/IEC 17025:2017 standards of forensic DNA testing, delivering FIGG results you can confidently use in court.
SNP triage™
DNA Labs International is the only forensic laboratory to provide SNP triage™. Forensic evidence is precious, and our proprietary method selects the most effective SNP analysis to maximize success without wasting samples.
SNP triage™ evaluates:
- DNA quantity (total, human, and bacterial)
- Quality
- Bacterial contamination
- Shallow sequencing
This tailored approach ensures each case receives the most strategic and scientifically sound path forward for maximum results.
Whole Genome Sequencing
WGS is the most powerful method of generating a SNP profile for FIGG. It is best suited for challenging sample types and typically produces the most distant genetic associations. We use the most sensitive industry assay available, designed by Astrea, for generating profiles from ancient DNA, and can even analyze mixtures with this powerful approach.
- Targets over 500,000 SNPs
- Results out to 5th cousins
- Best for challenging samples
- Uses the Illumina NovaSeq 6000
ForenSeq Kintelligence
ForenSeq Kintelligence is the most effective method for generating investigative leads for highly contaminated or degraded samples. We have successfully retrieved leads from samples with a degradation index in excess of 1000.
- Targets 10,230 human-specific SNPs
- Best for contaminated or low-quality samples
- Results out to 3rd cousins
- Free uploads to genealogy databases
- Uses the MiSeq FGx Sequencing System
SNP Array
The Whole Genome SNP array is the original method of generating a SNP profile for FIGG testing. It is the most cost-effective option for high-quality, single-source samples and is ideal for target or reference testing. DNA Labs International offers in-house reference testing at a low cost, using our Secure SNP™ kit for enhanced security and convenience.
- Targets over 500,000 SNPs
- Best for high-quality samples and reference testing
- Results out to 5th cousins
- Uses the Illumina iScan
