For my biopsy, they told me 6-8 weeks, but had some results completed after 2 weeks. The rest of the results were done by week 6. Mine was an in-house situation...which is not common. Many hospitals send their skin punches to Therapath.

The should be able to examine the sample to rule out vasculitus and amyloidosis; they will also examine the quality and quantity of nerve fibers. I think I also had to avoid any type of anti-inflammatory before the test. And make sure you think about the spots that hurt the most and have them take the sample from that leg. Good luck!
