A DNA case review begins with an initial examination of the DNA report issued by the crime laboratory.   The content of a DNA report should contain, at a minimum, standardized information that is dictated by the laboratory accreditation agency.   

Overall a DNA report should include sufficient information to determine the strength of the results and conclusions as determined from the laboratory data.  If a report was adequately prepared it is possible to assess a case without extensive discovery of raw data and other materials from the laboratory.   A report that lacks standard information or that presents conclusions that are unclear or unsupported by data, or lack thereof, could be a concern and a detailed review of the laboratory data and worksheets would be warranted.  

Based on industry standards, a DNA report should contain the following information:

  1. a complete description of all evidence items obtained for DNA analysis;
  2. an intact, unbroken chain of custogy;
  3. a description of all work conducted by the laboratory related to the DNA analysis.  This includes physical examination of the evidence and serological analysis (blood, semen, Saliva);
  4. results from microscopic analysis (sperm verification) whether positive or negative;
  5. results from all DNA analyses conducted;
  6. a clear statement of conclusion with supporting statistical analysis;
  7. information about any unusual procedures or data interpretations, or any problems related to the quantity or quality of the DNA obtained for analysis;
