This value has been subtracted from the patient's displayed TB and Mitogen results. Lower than expected results with the Mitogen tube
The nil tube value is subtracted from the values of the mitogen, TB1, and TB2 tubes for the final result of the respective tubes. Mitogen or Positive Control Tube (purple cap) The mitogen, or positive control, tube contains a mitogen (phytohemagglutinin-P), which is a nonspecific stimulator of T-cells.

The MITOGEN-NIL value serves as the positive control for the patient specimen, demonstrating successful lymphocyte activity. The TB1-NIL tube specifically detects CD4+ lymphocyte reactivity, specifically stimulated by the TB1 antigens. The TB2-NIL tube detects both CD4+ and CD8+ lymphocyte reactivity, stimulated by TB2 antigens.
Dispense blood into tubes in the following order: Nil, TB1, TB2 and Mitogen.
