A New Version of FaSTR™ DNA Is in the Works

The STRmix team is working on a completely new version of FaSTR™ DNA containing major upgrades designed to further strengthen the expert forensic software’s ability to rapidly analyze DNA profiles and assign a Number of Contributors (NoC) estimate. 

The upcoming version of FaSTR™ DNA, which is expected to be released later this quarter or early in the third quarter of 2026, brings significant enhancements to features across the software, including artefact detection, annotation, project management, reporting, and information display, as well as the ability to estimate NoC for Y-STR profiles.

Like previous versions of FaSTR™ DNA, the new version will combine an intuitive, user-friendly graphical interface with easily understandable and laboratory-customizable rules to speed the analysis of raw DNA data generated by capillary electrophoresis instruments and standard STR DNA profiling kits and assign a number of contributors (NoC) estimate. It will also contain numerous improvements to the analysis experience and workflow efficiency as well as enhancements to reporting and the seamless integration with STRmix™.

FaSTR™ DNA works by applying a set of fully configurable rules to streamline the analysis of STR DNA profiles. In some instances, DNA analysis is more complex, and automated heuristics (analysis rules) alone may not be able to resolve all profiles. Where the intervention of a DNA analyst is required, FaSTR™ DNA readily provides comprehensive details related to possible ambiguity of a peak (i.e. stutter type, ratio and composition, pull-up proportion, artefact detection etc.) and signals a requirement for the DNA analyst to make a decision. It then records and highlights changes made by the analyst.
