What does serology primarily analyze?

Serology primarily focuses on the analysis of blood, semen, saliva, and other bodily fluids to assist in identifying substances and potential biological evidence in a crime scene investigation. This branch of forensic science studies the properties, composition, and interactions of these fluids to ascertain details about a crime, including potential suspects or victims through their biological markers.

The analysis can reveal whether particular biological fluids are present at a crime scene and can often lead to conclusions about the presence of individuals, their involvement in the crime, or links between different pieces of evidence.

Other options like examining the impact of narcotics on behavior, analyzing fibers and hair, or utilizing DNA profiling techniques, while important in forensic science, do not fall under the scope of serology. These areas focus on different aspects of forensic analysis and require distinct methodologies and expertise.
