Bloodstain Pattern Analysis

Please try to imagine. When you enter the crime scene, the first thing you see is blood. It spreads to walls, floors and ceilings. Now no one else can know the information that this evidence holds, but people studying blood, how it works, patterns of blood, what they all mean, much evidence to study there is. By observing the blood pattern, they can find more about crime and what happens. Blood has five major categories: passive, shock splash, migration, other and potential.

The basic course of blood type analysis is the blood type basic analysis course. It is taught in many government agencies and private institutions. Curriculum standards are developed by the International Blood Group Inspection Analysts Association (IABPA) for the following purposes. Investigators, criminal site technicians, forensic engineers, other criminal and medical legal investigations and persons involved in the crime scene. This course aims to develop the foundation of the blood group analysis method.

Blood type analytical science solves practical problems by applying scientific knowledge of other fields. Blood pattern analysis utilizes biology, chemistry, mathematics, and physics as scientific fields. As long as the analyst follows the scientific process, this applied science can generate powerful evidence that makes it an effective tool for researchers (Fisher, 2003). Blood is a partially alkaline liquid composed of water, cells, enzymes, proteins, and inorganic substances. It flows through the entire vascular system and carries nutrients, oxygen, and waste products.

Blood group analysis is a technique in the field of forensic science. This technique of using blood as evidence is not new; however, the application of modern science has made blood analysis more reliable (Wikipedia). The arrest of criminals and criminals will not be a problem as long as advances in current technology and DNA analysis become available to law enforcement agencies (Wikipedia). Research on blood pattern analysis of forensic science solves many practical problems by applying scientific knowledge of other fields
