In TB patients, IFN-γ, TNF-α and IL-10 productions were detected after stimulation with PPD (median 325, range 22–1389; median 179, range 0–1178; median 12, range 0–182 respectively), ESAT-6 (median 13, range 0–4597; median 179, range 0–1679; median 65, range 0–191 respectively) and Erp (median 11, range 0–245; median 652, range 0–1961; median 228, range 0–1662 respectively). Here, IFNG is linked to tuberculosis.
