The way we interpret it is, there should be a difference of more than O.35 IU/ml, between TB antigen ( 0.479 in your case ) and nil antigen (0.040 ). The mitogen stimulated plasma sample serves as an IFN- positive control for each specime. A test is considered positive for an IFN- response to the TB Antigen tube that is significantly above the Nil IFN- IU/mL value.
