QuantiFERON-TB Gold measures the cell-mediated immune response (cytokines) to very specific TB antigens. The test is performed by collecting whole blood (1 mL) into each of three blood collection tubes. When the blood of an infected patient is stimulated with the M. tuberculosis-specific antigens in QuantiFERON-TB Gold, their T-Cells respond by secreting a cytokine called IFN-y. The IFN-y concentration in the plasma is determined using a sensitive ELISA.
