Ok, I really need to get this off my chest:
To all the people saying, "That could be Sasuke's dna, not Karin's!",it is 100% possible to determine whether a piece of dna come from a man or a woman. If the dna was in fact Sasuke's, it would've likely shown a Y chromosome peak on Suigetsu's dna test. So unless Suigetsu is completely ignorant of this fact, the sample most likely came from a woman.
I agree with other posters that the thing in the box was a piece of an umbilical cord. While Karin liked to hoard things as part of her Sasuke obsession, I doubt she wouldn't gotten her hands on something like that.
