Blood splatter, volume and interpretation

Splatter - The impact of spilled blood on surfaces. The pattern of the impact can provide vital information about the source of the blood. Blood spatter can help determine the size and type of wounds, the direction and speed with which the perpetrator or victim was moving, and the type of weapons used to create the blood spill.

Volume - A test designed to show the quantity of blood shed in a particular area. Also designed to show how much blood was shed to create a given stain or blood spatter pattern, and the amount of time needed to create that stain.

Interpretation - The interpretation of size, shape, orientation, and distribution of bloodstains on various surfaces, and what information can be derived from the proper interpretation of the stains.

Castoff Blood - Blood that travels from a source due to the movement of that source. A bleeding person will cast-off blood, as will a weapon or other item that is in movement.
