  1. By Courtney Daily Serologist forensic September 10, 2008

  2. What type of serologist Evidence does a analyze? blood And other bodily fluids.. such as semen, sweat and saliva

  3. Educational Requirements To become a Chief serologist one must go through specific schooling To achieve required educational levels Such as.. Bachelor’s Degree (the minimum) OR M.D. (master’s Degree) OR Ph.D Degree ..in natural science Biology/chemistry

  4. Study time Reading, practice, moot court proceedings Earning a degree and requirements (pretend/practice court case) Extensive on the job training, shadowing under the supervision of an expert All preparing the soon to be serologists with education that will prepare them for real life situations and investigations Training.. After classroom education Its time to train Students undergo real life training exercises For a more “hands on” experience, Students Work on real case studies under Professional supervision

  5. technique For analyzing evidence Fluids are tested and analyzed to determine what The substance is (Blood, sweat, semen, saliva) The suspected blood is then sprayed with a solution that changes coloUr when it reacts with haemoglobins or peroxidase in the blood Another test that can be done is spraying blood with luminal spray, making any residue containing bloodglow in the dark as well as pick up on traces of blood that may have been scrubbed away. A serologist is able drawl conclusions through a detailed inspection of the victim's spatter patterns Samples and testing solutions are placed into small wells on a gel-coated glass Plate. After the two defuse towards each other, the blood can be determined whether it’s human or not. If the sample is human blood, it will contain human antigens and where the two solutions meet on the gel-coated plate, a noticeable band forms.

  6. OF BLOOD investigation types.. Considering there are over 100 different antigens in the human blood it would be unnecessary and time consuming to test each and everyone.. SOO.. Serologists investigate a series of blood testing systems for quicker results, a common one being the ABO Blood Type System Serologists check red blood cell’s surface for two antigens (A and B) The blood type is named after the antigens it contains: A, B, AB and O Testing of the blood requires 2 solutions, one containing antibodies to type A and the other to type B. The first solution contains type A antibodies and if mixed with type A blood, will form clumps. The second solution contains type B antibodies and if mixed with type B Blood will form clumps. If blood reacts to both the first and second solutions, then the blood is AB because both antigens are present in the blood. The O blood type does not react to either solutions and can there for be classified if blood does not react in the experiments. (Serologists note any blood clumps formed when the same type of antigen meets the same type of antibody, and can then conduct an experiment on the blood Sample to determine it’s blood type)

  7. Classifying Finer detail Blood with After the blood type is determined, serologists are able to classify the blood type as negative Or positive + (Positive) By placing the positive sign before the blood type indicates The presenceof blood protein within the blood known as the Rh factor (named after the Rhesus Monkey, where it was first recognized) - (negative) By placing the negative sign before the blood type indicates the Absence if blood protein within the blood An antibody solution is used on the Rh protein. If Clumping occurs, the protein is present Causing the indication of finer blood type groups: A+, A-, B+, B-, AB+, AB-, O+ and O-

  8. “Judge Vacates Case study: Wrongful Rape Conviction ” Forensic serologist saves the day! “Marlon Pendleton was convicted of rape in 1992 based on victim identification. He maintained his innocence and worked independently for several years on his Case until Northwestern University School of Law Center for Wrongful Convictions took him under their wing. Post-conviction DNA testing was conducted under court order at SERI. Chief Forensic Serologist Brian Wraxall found semen on the remaining traces of the original swab and obtained a DNA profile of the semen donor who was not Marlon Pendleton. After serving 12 years in prison, Mr. Pendleton was exonerated and released.” Forensic serologist ran test of semen and found that the DNA of the semen did not Match that of the man put in jail. The falsely accused killer was released and the real Killer was caught and put in jail.

  9. Interview: Serologist Kevin Kosiorek gives her insights on serology Q: So what is it like to see dead people everyday? Does it gross you out? A: “Dead people don’t really gross me out.” Q: Is it like watching a CSI episode? A: “It’s not like ‘CSI’ when you see a dead person every day.” Q: DO you have any other jobs? Or is this your full time job? A: “We respond to a lot of crime scenes, even in the middle of the night.. I’m a scientist. I use science every day at my job.” Q: Can you tell the difference between and ketchup and blood? A: “If there’s a stain on the wall and I think it’s blood, we look at the stain and we say ‘no, it’s ketchup,’” “Without doing the tests, that is impossible.”

  10. Q&A: How he viewed life as a serologist Walter McCrone What he would have to say about serology What’s your educational background? “I received my bachelor’s degree in chemistry and a PH.D in organic chemistry at Cornell University. I completed two years of post-doctoral work there” What’s your typical day like? “I’m like any other person, I wake up, eat my breakfast and go to work. But My Work is a little bit more exciting than sitting in a cubical.” Do you have any other jobs? “No, I am passionate about what I do, and I couldn’t imagine doing anything but this.”
