Mucosal biopsy

Mucosal skin biopsy is the removal of a small piece of skin or mucous membrane. The sample can be retrieved in several ways: a shave biopsy (scraping or shaving a thin layer), a punch biopsy (using a needle or punch to obtain a small, but deeper, sample), or an excision of tissue (cutting to remove a piece of tissue). The sample is sent to the laboratory to isolate and identify organisms that cause infection.
