Definition    Return to top

Carpal tunnel biopsy is a test in which a small piece of tissue is removed from the carpal tunnel (part of the wrist).

How the Test is Performed    Return to top

The skin of your wrist is scrubbed and injected with medicine that numbs the area. Through a small cut, a sample of tissue is removed from the carpal tunnel. This is done by direct removal of tissue or by needle aspiration.

Sometimes this procedure is performed at the time of carpal tunnel release.

Fasting may be advised for a few hours before the test.

For infants and children, the physical and psychological preparation you can provide for this test depends on your child's age and experience. For specific information regarding how you can prepare your child, see the following topics:
