Bloodstain pattern analysis

Since 2008, IGNA has been offering bloodstain pattern analysis in conjunction with papillary traces and DNA analyses. Once again, IGNA is a pioneer in the field, as the laboratory was the very first French private laboratory to introduce this type of expertise.

Blood traces are systematically analyzed under rigorous principles (bloodstain taxonomy). This approach enables the detection of reference samples, critical according to the investigation. It also enhances efficiency while reducing the cost of analysis.


Our skills

  • Choosing and selecting reference samples based on the case’s context
  • Defining the most probable case-scenario (blow, nature of the weapon, localization of the wounds, position of the protagonists, etc.)
  • Statement compatibility examination


The service we provide

  • Searching for visible or latent blood traces
  • Analyzing the shape and pattern of the marks
  • Studying photo boards and objects sealed as evidence
  • Intervention on crime scenes and reconstructions
  • Forensic summary or review


Further explanation

This technique, established in the late 19th century, was only developed in the 1950s in the United States and very recently in France.

While DNA tests make it possible to determine the protagonists of a case, pattern analysis provides decisive insight on what actually occurred. Pattern analysis, in conjunction with DNA, is used to measure the bloodshed, to identify the perpetrator or victim and the most probable case-scenario.

As a pioneer in the quality approach of this discipline, IGNA’s blood pattern analysis is accredited to the NF EN ISO CEI 17020 standard since August 2014 (accreditation N°3-0943).
