IGRA (T-SPOT. TB or QFT-GIT) screening strategy for diagnosis of presumed latent TB infection (LTBI). A decision tree for the diagnosis of LTBI using the IGRA (T-SPOT.TB or QFT-GIT) alone in a single test strategy. Square nodes represent decision branches, circular nodes represent chance branches and triangular nodes represent terminal branches. The same decision tree was used for both versions of IGRA single strategies as they both have identical screening steps in each scenario.
