Skin biopsy procedure

A cutaneous nerve/skin biopsy is a very simple procedure that is performed in the outpatient setting and takes 10 to 15 minutes. First, the skin is thoroughly cleaned and a small injection of a local anesthetic to numb the skin is made. Then, a sample of skin is taken by a biopsy from the numb area of the skin. Finally, a band-aid dressing is used to cover the biopsy site. Generally, the skin heals easily within one to two weeks. The risk of bleeding or infection is extremely low. Patients who are anticoagulated with INR > 2.5 should not be biopsied.
