Supporting Your Laboratory During Probabilistic Genotyping Implementation: from Validation to Admissibility

Monday September 23rd, 2024 // 8:30 am - 5:00 pm // JW Marriott Hill Country, Room Grand ABCD

Standard Registration$345.00
Student Registration$195.00

Fee includes breakfast, lunch, breaks and handouts


Forensic laboratories are increasingly adopting probabilistic genotyping methods for the interpretation of DNA mixtures. Guidance for the validation and implementation of PG methods is evolving, with new documents being released after laboratories have implemented software. These include guidance from OSAC, ISFG, ENFSI, and NIST.

This workshop will cover the key recommendations for internal validation. We will discuss experimental design to meet the recommendations, summarize published material addressing these key issues, and discuss common challenges to the use of PG methods. Using interactive engagement, we will provide the audience with strategies to address new guidelines and to prepare for admissibility hearings for PG software.


Learning Outcomes:

  1. To understand the relevant standards and recommendations for validation
  2. Gain an appreciation of what data is publicly available to support Probabilistic Genotyping
  3. Support your laboratory to effectively address common challenges to the use of Probabilistic Genotyping (e.g. relatives, “factor space”, source code availability, activity level propositions)


Intended Audience:

This workshop is intended for DNA analysts, supervisors, technical leaders, attorneys and judges. Some knowledge required.
