If someone has had ncv/emg and skin punch biopsies come back clear does that mean they don't have neuropathy? Are there any other tests they should do? I asked Therapath if they indicate the condition of nerve fibers and they said no. Why would a company that offers this test not indicate condition of the nerve fibers? Is knowing the condition of the fibers very important? I still waiting for my skin biopsy results to come in.
