I spent the five happiest years of my life in a morgue. As a forensic scientist in the Cleveland coroner’s office I analyzed gunshot residue on hands and clothing, hairs, fibers, paint, glass, DNA, blood and many other forms of trace evidence, as well as crime scenes. Now I'm a certified latent print examiner and CSI for a police department in Florida. I also write a series of forensic suspense novels, turning the day job into fiction. My books have been translated into six languages.

Figuring out which is which isn't really that hard. Doing it might be, but it's usually not hard to figure out.
Hope that helps!

The title 'forensic scientist' doesn't mean anything in particular--job titles will vary by the agency. It would be better to major in a natural science or in forensic science so you could get as much lab experience as possible, but the only way to know for sure what the job requirements are is to call the place(s) you want to work and ask.
Yes, we do it every day.
Wow I am sorry I somehow didn't answer this question!! In my experience we do a presumptive test for both and then send to DNA testing because they will confirm the presence of DNA in the quantitative step. We do have the OBTI test for human blood but there's no reason to do it u less we're in a huge hurry to confirm human blood.
