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, which is used throughout the world in its various formats to screen cattle, other animals and people for TB. It’s the internationally accepted standard for detecting Mycobacterium bovis (M. bovis) infection in live animals. Rather than detect the bacterium itself, tests for bovine TB in live animals generally detect and measure the animal’s immune response to the bacterium.
