Thanks for the clarification, Cheryl. Yes, O-bands are not required if everything else pans out nicely . . . it's when it doesn't that they go looking for them.

When people don't have what is needed, the neuro sometimes sends them for a LP to look for O-bands. One is not enough to support a MS dx, in and of itself . . . but two would be more convincing, with either two documented clinical attacks, and/or a MS-type lesion(s) and i.e. one clinical attack, etc.
