Reactivos quimioluminiscentes para la localización de sangre en las escenas delictivas: Lumiscene. Prueba comparativa de sensibilidad

The correct blood location in crime scenes is one of the most crucial and complex aspects of the crime scene investigation. It is closely related to the correct choice of the chemiluminescen reagent for each occasion. Each one of these reagents has a different sensitivity level to the blood samples. Based on this premise, 80 passive bloodstains have been generated from 10 variable dilutions, which have been pulverized with 4 different reagents in order to determine how their results defer and which one is more sensitive. The collected data shows that the sensitivity of Lumiscene and Bluestar Forensic Magnum far exceeds the ones obtained under the same circumstances with other tests such as Luminal or Bluestar Forensic. It also shows that the differences among them are perceptible also in aspects like intensity and duration of the emitted luminescence.
