Hello Chelle,
Yes, I was diagnosed based on a positive LP (o-bands), neuro exam and symptoms. However, during the whole diagnostic process I was in a severe exacerbation (relapse, attack, flare-up)...it was very obvious something was wrong.
Depending on the lab that ran your LP results 2 o-bands can be considered normal, you will need to see what your Neurologist says to know for sure.
Best wishes
