Satellite spatterSmall droplets of blood that are distributed around a drop or pool of blood as a result of theblood impacting the target surface.Arterial sprayResulting from blood exiting the body under pressure from a breached artery. Can travel longdistances.Chemical that is used by forensic investigators to detect trace amounts of blood left at crimescenes, as it reacts with iron found in hemoglobin.A presumptive test for blood. Blood willl turn a blue color when mixed with benzidine.Benzidine is a known carcinogen and was used more in the past to test for blood.Bloodstain pattern created when blood receives a blow or force resulting in the randomdispersion of smaller drips of blood. Results from blood projecting through the air and areusually seen as spatter but may also include gushes, splashes, and arterial spurts.A chemical used to react with blood stains as a presumptive test. It will fizz and change colorsas it reacts with proteins.A chemical that is used as a test for the presence of blood. A positive result for blood makesthe phenolphthalein, which is clear, turn a bright pink color. Positive results are not limited tohuman blood.Blood that is blown out of the nose, mouth, or a wound as a result of air pressure and/or airflow which is the propelling force. It is usually caused by blood from an internal injury mixingwith air from the lungs and being expelled through the nose, mouth, or an injury to the airwaysor lungs. It tends to form a very fine mist and small air bubbles are typically found.A bloodstain pattern created when blood is released or thrown from a blood-bearing object inmotion.A chemical test for blood that is a presumptive test that can replace phenolphthalein. A greencolor will be produced if blood is present.In medical and forensic science a presumptive test either tells you that the material is presentor not present.Includes both forward spatter from the exit wound and back spatter from the entrance wound.Will vary depending on the caliber of the gun, where the victim is struck, whether the bulletexits the body, distance between the victim and the gun, and location of the victim relative towalls, floors, and objects. Typically, forward spatter is a fine mist and back spatter is larger andfewer drops.A bloodstain pattern created when an object moves through an existing stain, removing and/oraltering its appearance.The directionality of a bloodstain or pattern which indicates the direction the blood wastraveling when it impacted the target surface. Directionality of a blood drop's flight can usuallybe established from the geometric shape of its bloodstain.
