The Forensic Biology discipline performs serological and DNA analyses of bodily fluids for the purpose of identification and individualization. The type of material typically examined includes, but is not limited to blood, semen, and saliva collected at crime scenes or from articles of physical evidence.
What is the difference between forensic biology and forensic serology?
In fact, in many laboratories they are included within the same unit, collectively titled Forensic Biology. In the forensic laboratory, serology analysis refers to the screening of evidence for body fluids while DNA analysis refers to the efforts to individualize body fluids to a specific person.
What is forensic serology used for?
“Forensic serology is the branch of forensic sciences dealing with identification and characterization of biological, evidentiary samples — such as blood, semen, saliva, sweat, breast milk and any other bodily fluids,” says Professor Sebetan.
How does forensic serology work?
The Forensic Serology Section is primarily responsible for the detection and identification of biological material (i.e., blood, semen, saliva, and urine) on physical evidence in order to: Link suspect(s) and victim(s) to each other and/or to the scene(s) Include or exclude potential suspect(s) or victim(s)
What is forensic DNA and serology?
In the forensic crime laboratory, “serology analysis” refers to the screening of evidence for bodily fluids, whereas “DNA analysis” refers to the efforts to individualize bodily fluids to a specific person. In most cases, bodily fluid identification is performed on evidentiary items before DNA analysis is attempted.
What is serology typing?
Forensic serology is the application of the study of blood, semen, saliva and other body fluids, to legal matters. The field generally is comprised of the detection of enzymes and antigens, as in the identification of seminal stains or blood typing (ABO and secretor status) and DNA typing.
What is the main job of a forensic serologist?
Determination of the type and characteristics of blood, blood testing, bloodstain examination, and preparation of testimony or presentations at trial are the main job functions of a forensic serologist, who also analyzes semen, saliva, other body fluids and may or may not be involved with DNA typing.
How is blood useful in forensics?
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.
How can you tell if blood is from a human or animal?
Current Test: DNA. However, DNA is not considered a confirmatory test for blood, semen or saliva. How it works: The Ouchterlony test is used to determine if a blood sample is human or animal through the comparison of its reactions to specific antibodies.
Who is father of serology?
Serology is the study of serums such as blood and other human fluids. In 1901 Karl Landsteiner, a researcher at the University of Vienna, published his discovery that human blood could be grouped into distinct types, which became known as the ABO blood group…
How do I become a forensic serology?
Forensic serologists need at least an undergraduate degree in biology, preferably with additional coursework in math and criminal investigation. Some law enforcement agencies may require advanced degrees as well, either in biology or in forensic science or criminal justice.
How long does it take to become a forensic serologist?
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.
How is blood detected at a crime scene?
Crime scene investigators use luminol to find traces of blood, even if someone has cleaned or removed it. The investigator sprays a solution of luminol and the oxidant. The iron in blood catalyses the luminescence.
What is a serologist?
a scientist who studies blood and other fluids from the body: The forensic serologist will be able to say where the blood came from.
Which type of blood cells are needed for DNA typing?
Red blood cells are used in the DNA typing of blood. Only some of the 50 states contribute to CODIS.
What type of evidence is blood typing?
Examples of class evidence include blood type, fibers, and paint. Individual Characteristics are properties of physical evidence that can be attributed to a common source with a high degree of certainty. Examples of individual evidence include anything that contains nuclear DNA, toolmarks, and fingerprints.
