• Analysts or investigators will typically soak up pooled blood, or swab small samples of dried blood in order to determine if it is human blood and then develop a DNA profile. This becomes critical when there are multiple victims.
The use of blood in forensic analysis is a method for identifying individuals suspected of committing some kinds of crimes. ... When scientists identify blood types, they rely on slight differences in the antigens, or protein markers on the surfaces of red blood cells in a
blood sample • What is the purpose of analyzing blood at a crime scene?
• The recognition and analysis of bloodstain patterns can yield useful investigative information. The general role of the Bloodstain Pattern Analyst in a criminal investigation is to assist in the reconstruction of those events of an alleged incident that could have created the stains and stain patterns present at a crime scene, on items of physical evidence recovered from that scene and on items of clothing that were present at the crime scene. In some cases, it may be necessary to conduct a bloodstain pattern interpretation using photographs. The usefulness of individual bloodstains and bloodstain patterns lies in their retention of information descriptive of the possible events that could have produced them.
