Term Description

The quantitative levels (corrected for background) for an IFN-gamma response by CD4+ T-helper lymphocytes stimulated by the presence of TB antigens, such as ESAT-6 and CFP-10. The amount of IFN-gamma may be measured by enzyme-linked immunosorbent assay and reported in IU/mL. Results are adjusted for background, heterophile antibody effects, or nonspecific IFN-gamma in blood samples.

Change Reason
Updated Component to include "by helper CD4 cells" to clarify that the IFN-gamma response is from CD4+ T-helper cells only in this assay. A newer assay uses this test as well as a separate assay to detect IFN-gamma response by both helper CD4 and cytotoxic CD8 cells. Changed Component from Mycobacterium tuberculosis stimulated gamma interferon release by helper CD4 cells^^corrected for background to Mycobacterium tuberculosis stimulated gamma interferon release by CD4+ T-cells^^corrected for background to be consistant with LOINC cell marker naming conventions.
