Course Objectives

  • To gain knowledge of The significance of serological evidence.
  • To know the importance of biological fluids – blood, urine, semen, saliva, sweat and milk – in crime investigations.
  • To apply knowledge of genetic markers in forensic investigations.
  • To know about forensic importance of bloodstain patterns

Learning Outcomes

On completion of this course, students will be able to understand :

  • The significance of serological evidence.
  • The importance of biological fluids – blood, urine, semen, saliva, sweat and milk – in crime investigations.
  • The usefulness of genetic markers in forensic investigations.
  • The forensic importance of bloodstain patterns

Course Syllabus

Common body fluids. Composition and functions of blood. Collection and preservation of blood evidence. Distinction between human and non-human blood. Determination of blood groups. Antigens and antibodies.
Forensic characterization of bloodstains. Typing of dried stains. Blood enzymes and proteins.
Semen. Forensic significance of semen. Composition, functions and morphology of spermatozoa. Collection, evaluation and tests for identification of semen. Individualization on the basis of semen examination.
Composition, functions and forensic significance of saliva, sweat, milk and urine. Tests for their identifications.

Unit 2: Genetic Marker Analysis
Cellular antigens. ABO blood groups.
Extracellular proteins and intracellular enzymes.
Significance of genetic marker typing data. Sexual assault investigations.

Unit 3: Bloodstain Pattern Analysis
