I carry a small spray bottle with peroxide in it and get down on my knees when blood is hard to find. Sometimes leaves have red spots on them and it's hard to tell by looking at it if it's blood or not, so I spray peroxide on it and in pine needles and such. The peroxide will let you know quickly. If it's blood, it bubbles with peroxide. Niffty trick.
