Forensic serology can be considered the process of examining and identifying biological evidence, which occurs prior to the individualization of the biological evidence. Individualization of biological evidence is used to determine whether or not a bodily fluid sample has come from a particular person. Blood and blood stains serve various roles in forensic investigations. What are some applications of blood evidence in forensic science, and what characteristics and tests are used to determine its presence?
Understand the Problem
The text provides an overview of forensic serology, specifically focusing on the examination and identification of biological evidence like blood and blood stains. It outlines various applications of blood evidence in forensic investigations and describes specific tests used to determine the presence of blood.
Answer
Blood evidence aids crime investigation through typing, profiling, and event reconstruction. Key tests include Luminol and ABAcard Hematrace.
In forensic science, blood evidence can help determine the time and cause of a crime, identify the victim or suspect, and reconstruct events. Characteristics used include blood type, DNA profiling, and the presence of specific antigens. Tests include presumptive tests (Luminol, Kastle-Meyer) and confirmatory tests (ABAcard Hematrace).

More Information
Forensic serology involves examining blood evidence to ascertain the events surrounding a crime, and plays a crucial role in exonerating the innocent or identifying the guilty.
Tips
A common mistake is confusing presumptive tests with confirmatory tests; presumptive tests only indicate the possibility of blood presence, whereas confirmatory tests provide definitive evidence.
