For decades, TB was diagnosed using tuberculin skin testing. Positive animals were removed, and TB would be successfully eradicated over time. The Interferon Gamma Release Assay aids in this process and, when paired with newly developed antibody tests, establishes a powerful set of tools for TB eradication. 

There are many ways to implement and organize a TB testing system. TB Gamma is a more expensive tool, thus it should be used in a maximally efficient manner. Certain scenarios describe the use of TB Gamma on a skin test-negative population. Other uses are for confirmatory testing. Also, if an animal cannot be tested twice because of geography or time constraints, TB Gamma can be used instead of the skin test. In yet another scenario, TB Gamma can be used to test young animals, approximately six months of age, to verify colostrum pasteurization success and other sanitary measures intended to prevent transmission to young stock.
