    It looks like the significance of anti GQ-1b antibodies of IgM type is not well established. The wikipedia page on antiganglioside antibodies mentions this but there is no reference provided. This paper says:

    MFS being Miller Fisher syndrome, a variant of guillain-barré syndrome, associated with these GQ-1b antibodies.

    Do you have any neuropathy symptoms?

    I have throbbing & burning type pain in my cervical-thoracic spine. Progressing profound muscle weakness mainly in face, neck, arms but also generalised weakness & moderate to severe fatigue. Enthesitis & a lot of muscle pain. Fibromyalgia.

    Brain fog & cognitive issues.

    Not much in the way of numbness & tingling. Occasionally in chin area, which a Neuro said some years ago was consistent with my osteoarthritis in neck area.

    CK normal. EMG & NCS normal. MRI Right shoulder showed torn Supraspinatus, torn labrum, mild bursitis, some unknown process on bone?
    No sign of muscle atrophy.

    Do you know if your total IgM levels are normal?

    As far as I know, yes. It's been awhile since I tested. My usual pattern is normal levels of IgG & IgM... slightly raised IgA.

    I'll probably repeat the Ganglioside Ab test in a few months time, out of interest. Also will ask my Integrative GP if can repeat Immunoglobulin levels.

    Neuro did not think my Ganglioside Ab (IgM) significant & he sees it quite often. Still noted it in my summary letter.

    Thanks for your input & link Halcyon. I've got similar on my Ross River Virus Serology. An Equivocal for IgM only then two months later a Positive for IgM only.
