Identyfikacja śladów krwi

Chemiczne metody identyfikacji krwi

Wynaczynienie krwi może nastąpoć w związku z różnorodnymi rodzajami zdarzeń w tym najczęściej na miejscu rozboju lub zabójstwa. Krew ta może mieć postać plam i rozmazów koloru czerwonego, brunatnego a nawet zielonkawego (w zależności od czynników i podłoża na którym występuje). Często również występuje sytuacja, gdy ślady krwi są niewidoczne z powodu występowania na śladzie mikroskopijnej ilości cząsteczek krwi. Abystwierdzić czyw badanym śladzie występują cząsteczki krwi niezbędne jest zastosowanie odpowiednich środków reagujących z cząsteczkami krwi. Substancje te przedstawione są poniżej.

 

Blood Search, Identification & Enhancement

The advent of DNA technology has dramatically altered the approach of forensic scientists towards individualization of bloodstains found at the scene of a crime. The search for genetically controlled blood factors in bloodstains has been abandoned in favor of characterizing biological evidence by selected regions of our deoxyribonucleic acid (DNA). This ability to individualize bloodstain evidence greatly enhances the significance that this type of evidence can have in a criminal investigation and the importance for the crime scene investigator to:

In order for the investigator to conduct a thorough and comprehensive bloodstain evidence investigation, it is crucial for him/her to not only know how to proceed, but to have access to quality products, supplies and equipment that will ensure that their mission will be accomplished.

 

 

Lumino l Invisible Blood Reagent with Spray Head

Luminol is a chemiluminescent substance that can be used as a presumptive test for the presence of blood. Making use of the peroxidase-like activity of the heme portion of hemoglobin, Luminol produces a bluish-white light that can be viewed in total darkness. Invisible blood stains react with the Luminol reagent by luminescing—darkness is essential. A useful test for searching large areas for blood, especially if the area has been cleaned up.

Sensitivity:1:100,000. Solution mix with spray head bottles available in tyree sizes or choose reagent powder only (makes 8 each, 4 oz. solutions).

LumaVison ™ Luminol Companion Illuminator Kits

Searching for trace blood evidence with Luminol requires the area being searched to be darkened. LumaVision™ uses RED light which sharpens Wight vision, allowing your eyes to adjust to the darkness. When the luminscence of suspected blood occurs with the application of Luminol, the user will see this process more readily. Once found, the next step is to photograph your suspected blood evidence. Set your tripod mounted camera over top of the luminescence, check the settings, turn off the LumaVision™, and take the required photos. The LumaVision™ features 6 powerful Light Emitting Diodes (LEDs) driven by 3 AA-type alkaline batteries. The light offers bright, medium and low intensity settings as well as fast, medium and slow strobe effect. A seventh LED provides low power yellow light. A single set of batteries offers 10-12 hours of continuous light at the bright setting.

Hexagon Obti

This rapid screening test presumes that a bloodstain is of human origin and helps the Investigator to determine whether or not to collect a sample as evidence. A positive result indicates a strong likelihood that the bloodstain is indeed human, and a lab analysis will later confirm or deny that presumption. The Hexagon Obti test detects whole blood up to a dilution of 1:1,000,000. As few as 500 red cells are required for a positive result.

Lumiscene Advanced Latent Blood Search Solution

Lumiscene is designed to be the most efficient search method for latent blood at a crime scene. When there seems to be nothing, lumiscene can be utilized to detect minute traces of blood, allowing additional recovery of critical DNA and blood pattern evidence. Lumiscene is easy to use; add two activator tablets, mix and use. No measuring required. Lumiscene offers more luminescent results than luminol and contains the lowest percentage of peroxide chemistry available, protecting DNA from degradation during processing. Lumiscene is the best choice to find the most evidence and protect DNA integrity.

CSair Forensic Air Compressor

As important as the choice of a blood search solution is the chosen application method. Irreversible damage to the original appearance of the bloodstain pattern as well as dilution of the sample can occur, making DNA testing difficult or impossible. CSAIR is the first compressor system specifically designed for the application of blood search solutions, such as Lumiscene. The CSAIR compressor produces continuous, contaminant-free air through the utilization of its unique carbon filter.

Features:

  • Minimum use of Lumiscene, reducing the risk of DNA dilution Or damage and blood pat tern distortion.
  • Continuous pressure and 32 ft. hose allow large areas to be screened for blood.
  • Quiet operation, enabling comfortable communication at the crime scene.
  • Both compressor and spray gun have stainless steel air path (no reaction with blood search solution and easy to clean).

LATENT BLOOD DETECTION KIT FOR DETECTION OF BLOOD PRINTS

In most violent crimes, a profusion of blood is usually a result. Blood prints can be found on the weapon, floor, furniture and victim. In many instances, blood prints are not visible due to background color or the weakness of the blood print itself. To render these latent blood prints visible, the BT001 offers an extremely sensitive method for detection and development of bloody prints on surfaces like plastic, wood, coated papers, metal and glass. Latent blond prints developed through the utilization of these reagents are very clear and chemically stable.

Hemastix® Blood ID Reagent Strips

Hemastix® are 3” plastic strip with a special blood reagent material at the tip. The strip detect the peroxide-like activity of hemoglobin in a substance. Simply rub the Hemastix on a moistened stain or across a swab that has a suspected dried blood sample on it. The reagent coated tip will turn a shade of green if hemoglobin is detected. Compare the color reaction to the chart on the side of the bottle to determine the level of hemoglobin in the sample. If the reaction is positive, take a photograph of the strip by the substance to document the reaction and retain the strip as evidence. Please note: Expired Hemastix® will generally still react to the presence of blood, but should only be used for training purposes. Also, Hemastix® will not detect the difference between human and animal blood.
