 NIJ Training Course for Forensic DNA Officers of the Court: Uninterpretable DNA Samples in a Laboratory Report

August 5, 2020
Review the YouTube Terms of Service and the Google Privacy Policy
See reuse policy
An interactive tool used to supplement the NIJ online training course entitled 'Principles of Forensic DNA for Officers of the Court', as outlined in the sixth learning module, 'Understanding a Forensic DNA Lab Report'. This brief animation shows how inconclusive or uninterpretable results found in an electropherogram lab report can be excluded as the source of DNA evidence.
  
  
          Transcript
When peaks are visible on an electropherogram,  but no dependable conclusion can be drawn from  them for one reason or another, the sample  is deemed inconclusive or uninterpretable.
