The basis of science is empirical testing, applying methods to data. Validation studies conduct such testing in order to establish a method’s reliability. Validation testing also helps determine error rates, comply with standards, show general acceptance, and satisfy Daubert’s legal admissibility prongs. This talk introduces the principles of forensic validation. It reviews the validation of Cybergenetics’ TrueAllele® probabilistic genotyping system, focusing on eight peer-reviewed studies.
