Random thought - so sasuke was using karin's blood to heal himself (repeatedly), and wouldn't this mean he's got at least a tad of it congealing around in his guts?
Scientifically speaking, red blood cells don't contain DNA in mammals. In birds they do, but not humans. You'd need a bone marrow sample (see my previous thread on edo tensei). So maybe he doesn't, but I'm not sure if kishi was planning this and whether or not he wikipedia'd red blood cells first x_x
