Bethesda, MD 20894, Web Policies QFT is the most clinically tested and proven IGRA. The QuantiFERON -TB Gold IT system uses specialized blood collection tubes, which are used to collect whole blood via venipuncture, which include a Nil control tube, TB Antigen tube and a Mitogen tube (positive control). *For a test to be considered positive, the TB antigen tube value minus the Nil tube value must be 0.35 IU/mL (FDA cleared breakpoint). By binding to these moieties, lectins often agglutinate several cells together. Value is well above the minimum breakpoint of 0.5 IU/ml known active malignancy, positive the.
