Why would you get a cold sore swabbed and cultured? I've never had that done. Two thirds of the world's population has the HSV-1 virus, so the chances are very high that the people around you are also infected. It makes sense to avoid kissing and sharing things like cups or toothbrushes, but you don't need to become a social leper if you have one.
A mild cold sore may not form a pus-filled blister and burst either; I've had ones which haven't done that.
PS: You can't keep on re-infecting yourself with the cold sore virus either. Once you get it once, you have it for life. There's no cure for it at the moment.
