Both forensic biology and serology are very important branches of forensic science. If forensic science is a banyan tree, then biology and serology are its two strongest branches. They are very important for criminal investigations through the identification and examination of biological evidence like blood, saliva, hair, semen, and other bodily fluids.
Whether it's a case of homicide, sexual assault, or accident, forensic scientists that specialize in biology and serology reveal the truth with the help of clues hidden in biological traces.
What is forensic biology and serology?
Forensic biology refers to the process of scientific examination of biological evidence in criminal investigations. Whereas serology is a subcategory that classifies bodily fluids and their role in linking suspects to crime. Forensic experts, with the help of these techniques, interpret the biological clues and provide support to the judicial process.
Prime areas covered under forensic biology and serology are as follows:
- Blood analysis and bodily fluids present at the crime scene
- Study of biological stains through chemical and microscopic methods
- Extraction of DNA and profiling with the help of biological samples
- Time identification and reason behind biological material deposition
- Having the appropriate knowledge of blood spatter patterns in violent crimes
Through the examination of these components, students obtain information on how biology helps law enforcement in resolving complex criminal cases.
Role of a forensic biology and serology expert
A wide range of laboratory and investigative tasks are performed by the professionals in this field, such as:
1. Examination of crime scene evidence
The crime scene investigators collect the biological samples and carry out examinations to determine their evidentiary status.
2. Testing in a laboratory
Forensic experts carry out chemical, microscopic, and immunological tests to find out different bodily fluids and biological materials.
3. DNA samples preparation
Suitable samples for DNA extraction are prepared by serologists and profiled after confirming the presence of biological material.
4. Documentation
Properly maintaining laboratory records is important because every test that is performed might later get scrutinized in court.
5. Testimony in court
Highly experienced forensic biologists on a frequent basis need to appear before court as expert witnesses in order to explain laboratory findings in simple, easy-to-understand language.
6. Quality assurance
As per laboratory protocols, chain of custody should be maintained, and ensuring evidence integrity is an essential part of their work.
Career opportunities
Diverse employment opportunities have been created with the growing use of forensic evidence.
Government forensic science laboratories
In both center and state forensic laboratories, there is a demand for forensic biologists and serologists to analyze evidence from criminal investigations.
