Guyana Forensic Science Laboratory

ABOUT THE DEPARTMENT

Biology is the science of life and living organisms. Forensic Biology is the application of biological analytical methods to legal investigations. It involves the examination of evidential items for the purpose of linking individuals to those items and the analysis of body fluids collected at crime scenes and from articles of physical evidence for the purpose of identification and individualisation.
