they didn't have that test available way back then, in the dark ages of my Dx.



I didn't even know about O-band testing until I read about all the LPs going on, here on MS boards, and somebody posted this:

OligoClonal Bands (Gamma Globulin Bands) - A positive finding from the chemical analysis of ImmunoGlobulin (IgG) found in Cerebrospinal fluid. IgG Bands indicates an Intrathecal production of antibodies. This signifies an Immune response to a nonspecific CNS Antigen.

IgG Banding is commonly found during a current or very recent exacerbation. It is present in 50 - 75% of patients undergoing a diagnosis for MS, and eventually in 87% - 95% of all MSers.
