The UOP Changelog v3.0.0 (2008-06-03) mentions this: "Changed the name of the useless item found on the ground in random Oblivion plane #6: "Blood Potion" -> "Discarded Daedric Blood Vial" (it's a misc. item not a potion so can't be equipped ie for vampire feeding, and has no known purpose but has a unique container which makes a nice player house decoration so didn't want to remove it from the game)"
Maybe have another look at the name change. "Discarded Daedric Blood Vial" makes it seem like the Vial has Daedric Blood in it, which is not something we know for sure. Or maybe the name change was supposed to say the Vial is of Daedric design? Anyway the name change could cause confusion for the quest "Blood of the Daedra".
All of this is minor and my native language is not english. So please have another look at it yourself. I found this because the change is also listed on UESP
