What type of analysis does forensic serology focus on?

Forensic serology primarily concentrates on the analysis of biological fluids, such as blood, saliva, semen, and urine. The main goal is to identify the presence of these fluids at a crime scene and determine their characteristics, which can provide crucial information about the circumstances of a crime and potential suspects. By examining these fluids, forensic serologists can derive essential data regarding the source, which can help in linking a perpetrator to a location or victim.

In contrast, while physical evidence like firearms or knives may be important in forensic investigations, they do not fall under the realm of serology, which is specifically about biological evidence. Similarly, digital evidence pertains to data from electronic devices and is outside the scope of serology. Although DNA extraction does relate to biological evidence, it is a more specialized process often classified under molecular biology or forensic DNA analysis rather than serology. Therefore, the correct focus of forensic serology is indeed the analysis of biological fluids for identification and characteristics.
