To improve the specificity of the control program C, the γIFN assay used in this control program is a combination of two tests: the PPD γIFN and the ESAT-6 γIFN. The modified γIFN test can be positive (both tests are positive), negative (both tests are negative) or divergent (the results of the two tests are discordant).
