TB testing cattle

The main screening test for TB in cattle in Great Britain is the single intradermal comparative cervical tuberculin test (SICCT). This is commonly known as the tuberculin skin test. 

White cow - Bovine TB

The bovine TB skin test is supplemented by the interferon-gamma blood test, or gamma test for short. This laboratory-based test is used alongside the skin test in known infected herds under TB restrictions.

Antibody or serological blood tests are used on a case by case basis in chronic and persistent TB breakdown herds that have not been resolved despite multiple rounds of skin testing and use of the gamma test.
