Key facts

  • Mycobacterium bovis tuberculin stimulated gamma interferon [Interpretation] in Blood Qualitative
  • Mycobacterium bovis tuberculin stimulated gamma interferon
  • Blood plasma collected from cattle having an optical density (OD) value for the M. Bovis result [LOINC 82511-7 ] > 0.100 above that of the avian result OD [LOINC 82387-2] and nil antigen result OD [LOINC 82509-1], indicates the presence of M. bovis infection. The assay is used as an alternative to the comparative cervical skin test and reduces the need for multiple farm visits. This term was created for, but is not limited in use to, the submitter's Bovigam Mycobacterium bovis Gamma Interferon Test Kit for Cattle, a blood-based in vitro laboratory test for bovine tuberculosis.
