The Role of Forensic Serologists in Criminal Investigations

Forensic serologists specialize in analyzing blood and other bodily fluids found at crime

scenes. Their expertise is invaluable when it comes to identifying whether a fluid is blood,

determining its origin, and understanding the circumstances under which it was

deposited.

What Does a Forensic Serologist Do?

At its core, forensic serology involves several critical tasks:

Identification of Bodily Fluids: Beyond blood, serologists identify saliva, semen,

1.

sweat, and other fluids that might be present at crime scenes.

Blood Typing: Determining blood groups can help narrow down potential suspects

2.

or victims.
