My theory is that Karin DID have something to do with Sarada's birth. Maybe she helped deliver Sarada? She could have taken Sarada's umbilical cord for Orochimaru seeing as he has a hard on for Uchiha DNA and umbilical cords have a shit ton of stem cells. Also people say it's Karin's because some Japanese mothers keep their child's umbilical cords but if that's the case why is in her desk? Also I'm not even sure that it was a umbilical cord at all it was hard to tell. Though I will say that whole "100% match" thing is stretching it. Just because the lines matched up doesn't mean 100%. i agree Karin had to at least be there for the birth if she has a sample of Sarada's DNA if its a umbilical cord or not i dont know like you said its hard to tell but from what Sueigetsu thought to himself its makes the most sense. And about Karin keeping the cord in her desk that is some thing i also said in a different thread as well as Orochimaru ordering her to maybe steal it for the Uchiha DNA especially if Sakura is the birth mother i mean regardless of her showing she is strong so Orochimaru might want her genes as well. i wouldn't say the 100% match is a stretch like i said it looks like it matches perfectly which wouldn't be possible if it was matching a parent's DNA to a child and i think the last few chapters put too much into genes and DNA for that to be a oversight

also want to point out one possible reason why there are no records of Sarada's birth other then the theory that Sasuke and Sakura were traveling when she went into labor maybe they kept Sakura's pregnancy a secret in case some one might have wanted to harm or kidnap the first born Uchiha in years
