Blood is a commonly encountered biological fluid in criminal investigations concerning a violent incident, and visual traces of the fluid on a suspect’s clothing can be diminished through laundering. This study aims to analyze the effects of laundering and the application of commercially available blood enhancement reagents commonly used to improve visualization of dilute bloodstains and their impact on DNA recovery. Enhancement reagents Hungarian Red, Coomassie Blue, Amido Black, luminol, Bluestar® Forensic Magnum, and aqueous Leuco Crystal Violet (LCV) were used to enhance human blood on cotton, polyester, denim, and wool following laundering. DNA was extracted from these samples using …
