As Stillhoping asked...why do you want to repeat it? In most cases, the biopsy is repeated AFTER the use of a treatment that has hopes of increasing density or repairing nerves...like IVIG.

Even if you did have a treatment that may change your biopsy results, you should wait at least 6-9 months...sometimes longer...all depending on the what treatment you have been using.

Can you give us a little more information, so we can better answer your question??
