Can information encoded with a one time pad be distinguished from random noise?

I understand that the cyphertext from a properly used one time pad cypher reveals absolutely no data about the encrypted message.

Does this mean that there is no way to distinguish a message encrypted with a one time pad from completely random noise? Or is there some theoretical way to determine that there is a message, even though you can't learn anything about it?
