Mitogen stimulated gamma interferon [Units/volume] in Blood

Mitogen IGNF Bld-aCnc

Definition

  • In the Quantiferon Gold test, the Mitogen-stimulated plasma sample serves as an IFN-gamma positive control for each specimen tested. A low response to Mitogen (<0.5 IU/mL) indicates an Indeterminate result when a blood sample also has a negative response to the TB antigens. This pattern may occur with insufficient lymphocytes, reduced lymphocyte activity due to prolonged specimen transport or improper specimen handling, including filling/mixing of blood tubes, or inability of the patient's lymphocytes to generate IFN-gamma.
