If cidp disease is suspected, what blood or lab tests show be done?

CIDP: Its controversial whether CIDP is a distinct disease or part of a syndrome. Labs can include CBC count, protein levels, sedimentation rate, antinuclear antibody, biochemistry profile, and serum and urine mmunoelectrophoresis, and nerve biopsy and EMG. There is a long list of diseases associated with CIDP including lupus, HIV, thyroid problems, diabetes and hepatitis.

Nerve studies: Typically, if the history and symptoms are suspicious for CIDP, your doc will have you undergo electrodiagnostic studies like electromyography where there are specific findings that point toward confirming the diagnosis. Sometimes you will also have a lumbar puncture to study the cerebrospinal fluid and a nerve biopsy. These are all more diagnostic than blood tests.
