I would not waste my time with the sudoscan because I had multiple scans that did not diagnose my small gainer neuropathy but the skin punch biopsy did. The skin punch biopsy is the gold standard test. Sudoscan tests perspiration/sweating and I also had an ankle brachial test which both missed my idiopathic SFN. A waste of time and money in my experience and opinion.
