Abstract:
Luminol is a valuable tool for crime scene examiners. The use of this reagent, primarily at crime scenes, allows the visualisation of occult or diluted blood, and the detection of small quantities of blood. Various different luminol formulations have been proposed over the years. In this study we have compared four different formulations with respect to luminescence and longevity. DNA profiling of blood treated with the four formulations with AMPFlSTR® SGM PlusTM and low copy number (LCN) DNA analysis allow us to make recommendations of the most appropriate luminol formulations to be used under particular case circumstances.
