[X-Men] Does touching Rogue's blood have the same effects as touching her skin?

Like, if somebody were to take Rogue's blood and put it in aerosol form, could it be used as a deadly chemical agent? 

If Rogue gives blood, what happens to the person who receives it?

Nothing, because her powers are connected to an area around her. Think of it like Superman's bio-aura. She's got one that's much tighter and easier to block. If the aura touches someone, it starts to leech off of them.

Her blood leaves that aura. It's no longer really a part of her. It's not 'alive'. It has no power.
