Forensic serology is a branch of forensic science that studies blood and other bodily fluids for crime investigations. For instance, it may be used to determine the presence or absence of blood, semen, or saliva at a crime scene. However, there are several other terms related to forensic serology that are frequently used in criminal investigations. These terms include serology analysis, blood analysis, DNA profiling, blood typing, and blood serology. All these terms are closely related to forensic serology and are often applied for the same purpose of determining the presence or absence of bodily fluids, and identifying suspects in criminal cases.
