Zar-pro fluorescent blood lifting strips were developed by a police officer to improve current methodology relating to processing bloody impression evidence.

  • Bloody Impressions are frequently found at the scene of violent crimes and used by forensic analysts to identify subjects.
  • Before Zar-Pro, there were no universally-accepted procedures for lifting or enhancing bloody impression evidence.
  • Many blood enhancement methods are often problematic and impractical for crime scene use.
  • Immovable and bulky objects may not be brought back to the laboratory for enhancement.
  • Impression evidence may only be photographed and not chemically enhanced due to limitations with some blood enhancement methods.
  • These lifting strips were developed to create a universally-accepted, easy-to-use, non-toxic method for lifting, enhancing, and preserving bloody impression evidence.
