The mitogen tube also serves as a control for indicating long or improper transport, incorrect blood handling and incubation. Tumor cells are also resistant to the hyperproliferation stress response. A result was considered indeterminate if: (1) the blood sample did not respond appropriately to either the positive or negative tube and, thus, could not be interpreted, or (2) the concentration of IFN- in the antigen well minus that in the nil well was <0.35 IU/mL but the concentration of the cytokine in the mitogen well was <0.5 IU/mL or (3 . 101-111. in the TB-antigen tube minus the value for the nil-control tube (TB-antigen minus nil value) was 0.35 IU/ml and when the TB minus nil value was 25% of the IFN-g concentration of the nil control.
