Determination of the type and characteristics of blood, blood testing, bloodstain examination, and preparation of testimony or presentations at trial are the main job functions of a forensic serologist, who also analyzes saliva, other body fluids and may or may not be involved with DNA typing.

Blood is not the only body product, which can be of use to the forensic blood grouper. The word serology comes from the ancient Sanskrit sara, meaning, "to flow". Today it is known that every fluid, which flows in the human body, can be identified: sometimes to prove the guilt of a suspected person, but also very often to protect the innocent. .
