A test is considered positive for an IFN- response to the TB Antigen tube that is significantly above the Nil IFN- IU/mL value. Incomplete data or improbable values were sent to the performing laboratory The light signal, and hence the amount of isoluminol-antibody conjugate, is measured by a photomultiplier as relative light units (RLU) and is indicative of the amount of analyte IFN-gamma present in calibrators, samples, or controls.
