Tuberculosis diagnosis by BCG inoculation tuberculin tests can be affected. In general the US approach is likely to result in more false positives and more unnecessary treatment with potentially toxic drugs; the UK approach is as sensitive in theory and should also be more specific, because of the use of interferon-γ tests. Under the US recommendations, diagnosis and treatment of latent tuberculosis infection (LTBI) is considered for any BCG-vaccinated person whose skin test is 10 mm or greater, if any of these circumstances are present: These have been reviewed in detail.

It is the ability to activate one's own argument for future defense and strengthen their existing attitudes through counterarguing (Pfau, 1997).
