Hey dreamer
So when I got my results back (a couple years ago) my ENFD was also normal - 8 at the calf and 9.71 at the thigh (they wouldnt give morphology because my age - 19 at the time). However - my SGNFD number in the thigh was significantly reduced (29.2) which was like one strike for SFN. Then I had a QSART test (http://my.clevelandclinic.org/servic...-testing/qsart here is a description) which also showed reduced sweat production in the thigh (which matched the skin biopsy SGNFD results). Did you also have SGNFD done with your biopsy? I guess what I am trying to say is that there are other ways to come to the same diagnosis!
