Forensic scientists test blood at a crime scene using the chemicals Luminol (C8H7N3O2) and hydrogen Peroxide (H2O2). if blood is present when they use these chemicals, it will glow with a bluish color in the dark.
I hope this helps.

Two examples of tests that can be done to detect blood at a crime scene are luminol testing, which involves spraying a chemical that reacts with blood to produce a blue glow, and presumptive blood testing using chemicals like phenolphthalein or Hemastix, which can indicate the presence of blood based on color changes.
