Urine, semen and blood contain fluorescent molecules, so they also show up under black light. Most biological fluids contain fluorescent molecules to help them glow. Although most bulbs also give off a faint violet glow, the majority of the light is outside the visible range. Typically, luminol only shows investigators that there might be blood in an area, since other substances, including household bleach, can also cause the luminol to glow.
