How do you test for CWD?

The only sure and practical way to diagnose CWD is through microscopic examination of the brain stem or lymphatic tissues of a cervid using immunohistochemisrty (IHC). A more rapid test using ELISA on lymph nodes is reliable as a screening method for the disease. A test for live animals, involving the removal of tonsils or rectal lymphatic tissue is currently in experimental and research stages. Testing for CWD is done by federally-approved laboratories; there is no quick test that you or your meat processor can perform to determine if your animal has CWD.
