Forensic serology thus is the study and examination of body fluids such as blood, semen, sweat, urine, saliva, fecal matter, and other fluids mainly for identification purposes in criminal/medicolegal investigations.

Forensic serologists assist in criminal investigations by analyzing blood, urine, saliva, semen and other bodily fluids found at crime scenes. Their work can identify possible suspects, determine cause of death and help detectives unravel the sequence of events surrounding a crime.

To become a Forensic Scientist, one must possess at least a 4-year bachelor’s degree in Forensic Sciences or related field with the relevant work experience of 1 to 2 years. If you intend to go for further qualifications, a professional certification takes about 1 year or more.

Required Qualifications & Training to Become a Forensic Scientist

1. Undergraduate Course (3 years):- B.Sc. in Forensic Science.
2. Post Graduate Courses (2 years):- M.Sc.
3. Doctoral Course (3 years):- Ph.
4. Top Forensic Science Colleges in India.
5. Top Universities for Forensic Science Abroad.

Forensic scientists often use techniques to identify blood types (blood typing) because an individual’s blood type isn’t affected by disease, drugs, climate, occupation, living conditions, or any other physical circumstances. Additionally, scientists use blood-typing to determine paternity.

5 Important Tools Used by Forensic Scientists

• Mass Spectrometers. There are a lot of trace evidence that can be gathered from a crime scene.
• High-Powered Microscopes.
• Chromatographs.
• Various Cameras and Photography Techniques.
• Various Light Sources.

criminalist in American English (ˈkrɪmənəlɪst ) an expert in the use of scientific methods to investigate crimes, specif. by collecting and analyzing physical evidence; forensic investigator.

Biological evidence refers to samples of biological material—such as hair, tissue, bones, teeth, blood, semen, or other bodily fluids—or to evidence items containing biological material (DNA Initiative 2012). Such evidence is frequently essential in linking someone to or excluding someone from crime scene evidence.

Non-fluid biological evidence, such as tissue, bone or hair, can also be transferred by direct contact and deposit. Blood, semen, body tissue, hair, saliva or urine could be transferred to a victim, suspect, witness, object or location through an intermediate medium.

The power behind biological evidence is its use in identifying victims or suspects, leading to establishing the presence of victim or suspect being at a scene. Types of biological evidence include body fluids, such as blood, semen, saliva, and urine, as well as skin and other types of tissues and organs.

Hair samples are primarily collected using tweezers. Fiber – Fibers are threadlike elements from fabric or other materials such as carpet. Fibers are useful in crime scene investigation because their origins can be identified. A carpet fiber on a person’s shoe can indicate the individual’s presence at a crime scene.

Hair samples are one of the most important resources in the forensic analysis of crime scenes, often providing valuable information that can help to lead to the identification of a suspect or victim. Hair can also be used to extract DNA for analyses that can help to narrow down who may have been involved in a crime.

The American Academy of Dermatology says that hair grows about 1/2 inch per month on average. That’s a grand total of about 6 inches per year for the hair on your head.

Hair shaft is consisted of three layers: cuticle, cortex and in certain cases medulla.
