Why is serology important in forensic science?
Serology allows the forensic scientists to segregate these bodily fluids when found at the scene of the crime and then perform a variety of tests on them in order to identify where these fluids originated from – or most importantly – who they came from.
What is the importance of blood in forensic science?
Properly collected and preserved blood evidence can establish a strong link between an individual and a criminal act. Blood evidence or the lack of blood evidence can also be used to bolster or contradict a witness statement or any statements that the suspect may make.
Why might forensics be important to forensics?
Forensic science is one of the most important aspects of any criminal investigation, as it can allow the authorities to do everything from positively identify a suspect in a crime to determine exactly when and how a crime occurred.
What is the difference between forensic biology and forensic serology?
Serology focuses more on fluid evidence, whereas biology relies more on collecting and analyzing fluid and genetic information such as DNA, bones to identify the criminals.
How do forensic scientists test blood?
Analysts or investigators will typically soak up pooled blood, or swab small samples of dried blood in order to determine if it is human blood and then develop a DNA profile. This becomes critical when there are multiple victims.
Why is blood an important biological evidence?
Blood is one of the most important biological traces that are often found on the crime scene. … Proper knowledge enables interpretation of results and makes it possible to get closer to the truth, solve that particular crime and bring the perpetrator to justice.
What components of blood are the most important to forensic scientists?
For forensic purposes, red blood cells and blood plasma, described below, are probably the most important types of evidence. From these two components, a complete blood typing profile can be made.
Why are white blood cell so important in forensic science?
Forensic scientists, for example those who work at Environmental Science and Research (ESR), are required to collect biological material from a crime scene. Blood is an excellent source of DNA. It is collected from the white blood cells (mature red blood cells do not contain DNA).
What is the main purpose of screening tests for blood and seminal fluid?
The most important reason for these tests to be non-destructive is the preservation of DNA evidence. Body fluids such as blood, semen, saliva, vaginal fluid, urine, and sweat all contain DNA evidence so it is imperative to develop identification tests that will protect this valuable data .
