single intradermal test
a test used in the field diagnosis of bovine tuberculosis. A small volume of tuberculin is injected intradermally, commonly in a tail fold, and observed at 72 to 96 hours for a significant increase in thickness of the skin. The tuberculin elicits a cell-mediated immune reaction at the site of injection in infected animals and the increased thickness of the skin is the consequence of infiltration into the site of T lymphocytes and activated macrophages.
