Forensic Serology is the study of bodily fluids as they relate to criminal cases and includes a DNA analysis. A forensic serologist would be interested in:
- Evaluating the DNA found in bodily fluids such as blood, urine, saliva, CSF,
and interstitial fluid.
- Reporting and testifying regarding the results of her analysis in a court of law
- Examining crime scene evidence for the presence of body fluids e.g. blood,
semen, hair, tissue, saliva, feces, and urine
- Evaluating and identifying the species of body fluids - is it human or a cat,
squirrel, insect or alien?!
- Performing PCR (polymerase chain reaction) and an analysis of STR (short
tandem repeat sequences) of both genomic DNA, or mitochondrial DNA
- Statistically evaluating the collected evidence
- Performing an unbiased analysis with appropriate scientific methods

CSI Cam: Seeing body fluids on canvas using blue light
We used a Rook Forensic Blue (450 & 470 nm) light source to see serological evidence (AKA bodily fluids). From left to right we're looking at semen, urine, blood and saliva. samples go from pure (non-dilute) in the top rown and become increasingly diluted in subsequent rows, This sample was created on a white canvas material in a lab by a local PD. An orange filter was placed over the lens in order for the camera to show the evidence. Orange goggles could also be used to see the evidence.
Motel room inspection using a blue light: Part 1
We checked out motel room in California using our FoxFury Rook Blue LED forensic light source (450 nm and 470 nm). Part 1 shows us inspecting a wall, bedspread, bed sheets, mattress and (gulp) the pillow. The camera has an orange filter placed over the lens to allow fluids to be seen. Please don't watch this if you have a hotel phobia.
