Forensic Serology

Forensic serology is the detection, identification, classification, and study of various bodily fluids such as semen, saliva, urine, breast milk, vomit, fecal matter and perspiration, and their relationship to a crime scene. A forensic serologist may also be involved in DNA analysis and bloodstain pattern analysis Serology testing begins with presumptive tests which gives the analyst an indication that a specific bodily fluid may be present, but cannot completely confirm its presence. Following the presumptive tests, are the confirmatory tests that confirms what the unknown substance actually is? The knowledge of serology will help in determining the origin of the biological fluids, whether of human, vegetable, or animal origin. Also helps in determining the blood type, secretor, and non-secretor status.
