In the process of working on a NIST Scientific Foundation Review on DNA mixture interpretation, our team gathered and studied the scientific literature on the topic and carefully considered principles and best practices. The report generated from our study will be discussed along with specific thoughts regarding case context and measurement and interpretation issues involving binary approaches and probabilistic genotyping.


Learning Outcomes:

  1. The literature and scientific foundations of DNA mixture interpretation
  2. Case context considerations in examining complex, low-level DNA mixtures
  3. Measurement uncertainty and reliability considerations for forensic mixture DNA interpretation involving binary approaches and probabilistic genotyping


Intended Audience:

DNA analysts and Technical Leaders
