this is the key difference between QuantiFERON Gold and T-SPOT. QuantiFERON Gold test measures the IFN-γ concentration via an enzyme-linked immunosorbent assay (ELISA), whereas, T-SPOT test measures the number of IFN-γ-secreting T cells via enzyme-linked immune-spot assay (ELISPOT...
BACKGROUND: Two commercial blood assays for the diagnosis of latent tuberculosis infection--T-SPOT.TB and QuantiFERON-TB Gold--have been separately compared with the tuberculin skin test. Our aim was to compare the efficacy of all three tests in the same population sample. METHODS: We did a ...

TBI is detected using interferon-y release assays (IGRA), such as QuantiFERON-TB Gold (QFT) and T-SPOT.TB, which measure the immune response to Mycobacterium tuberculosis antigens using similar methodologies [3]. Although widely used, even in low M. tuberculosis-transmission settings [4,5],...
Whereas, in the „high risk for TB“ group, the TST was positive for 60%, but the T SPOT TB test, only for 17.8%. Meanwhile the results for the „low risk for TB“ group were 65.4% and 9.6%, respectively. A correlation between the TST and T SPOT TB was obtained in the "...
Two IGRAs are now available as commercial kits: the T-SPOT.TB® test (Oxford Immunotec, Oxford, UK), and the QuantiFERON®-TB Gold® (Cellestis Ltd, Carnegie, Australia) assay. The QuantiFERON®-TB Gold (QFT-G) assay is available in two formats, a 24-well culture plate format...
