Please tell me if there is a simple test to determine if blood is the residue on surgical instruments or rust. Very important. Sales Rep. said it was rust on his instruments, it looked like blood to me that was not cleaned from previous surgical case and was Autoclaved ( a high temp. steam process to sterilize surgical instruments)? I appreciate your time. Janice

Yes, there are several, some are tests where a color change occurs and others cause fluorescence. Those that cause a color change are benzidine, O-Tolidine, phenolphthalein, tetramethylbenzidine, and leucomalachite green. Those that cause fluorescence include fluorescein and luminol. These are screening tests and if positive, confirmatory testing would follow: the Teichmann Test and the Takayama Tests. Then further testing would reveal whether the blood was human or not. This is covered i greta detail in two of my books: Forensics For Dummies and Howdunnit: Forensics.

I want to be a blood splatter analyst when I’m out of school and need expert advice. I need to know what exactly I should be studying, including things in criminal justice. What do I need to know about chemicals? How do I learn about the way the blood flows through the body and exits?

Take some classes in chemistry, physics, biology, and math and you’ll be set. And then try to get a part-time job at a hospital lab or a crime lab where you can learn how these labs work and how to use the various pieces of equipment.
