Luminal is a substance that is used in glow sticks to make them glow. It is also used by forensic investigators to detect blood at crime scenes. Luminal is a dangerous substance and it is not safe at all for the blood stream. You should avoid contact with the skin and mucous membranes.
Luminol
The basic idea of luminol is to reveal blood traces with a light producing chemical reaction between several chemicals and hemoglobin.
In Season 6, Episode 7 of CSI: Crime Scene Investigation titled "A Bullet Runs Through It, Part 1," luminol is used to detect blood in a crime scene. The forensic team sprays luminol on a crime scene and discovers blood spatter patterns that help them piece together what happened.
Investigators may spray a crime scene with hydrochloric acid (HCl) before using luminol to help remove any potential contaminants or residues that could interfere with the reaction of luminol with blood. This ensures a clean surface for the luminol to detect any hidden blood traces effectively.

Luminol is a chemical that can be used to detect blood even when it has been wiped clean. It reacts with the iron found in hemoglobin, producing a blue glow which indicates the presence of blood.
Luminol is a common chemical used to detect blood at a crime scene. It reacts with the iron in hemoglobin, causing a blue glow under UV light. This can help investigators identify blood even if it has been cleaned or hidden.
they use luminol spray and an ultra violet light
The chemical reagent that makes blood glow luminously is luminol. When it reacts with the iron present in hemoglobin, it produces a blue light that is visible in dark conditions. Luminol is often used in forensic investigations to detect blood at crime scenes.
No it stays blue, it only turns blue in the presence of blood

It "works" better with neither; it reacts equally well to both, even though the blood of lower vertebrates, such as birds and lizards, has nuclei, whereas the blood of mammals does not. Luminol will react with most substances that have large amounts of iron. It will even react to horseradish.
