My biopsy was done at Johns Hopkins and the results do not include numeric values. The ankle site was found to be "devoid of nerve fibers", above the thigh was "reduced with a patchy distribution" and the upper thigh was " segmented and breaking down". Diagnosis was a severe, progressive, length dependent neuropathy. I also have abnormal EMG/NCS that show advanced LFN. Final conclusion was Charcot Marie Tooth (hereditary neuropathy) probable type 2 because of axonal damage.
Once I had a diagnosis there was no interest in further testing and no treatment beyond pain management.
