LOINC display name : Mitogen stimulated gamma interferon Qn (Bld);
LOINC long common name : Mitogen stimulated gamma interferon [Units/volume] in Blood;
LOINC short name : Mitogen IGNF Bld-aCnc;
LOINC description : 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.;
