[Other] Blood starts pouring from the walls, horror-movie style. What happens if I do a DNA test?

It is usually an animal's blood. However if its human, its most likely no ones, and is cursed.

So a DNA test would turn up with the species, maybe the type, and no DNA matches. It'd be like a randomized DNA sequence, with a pattern not intentionally the same as anyone alive.
