71776-9 Gamma interferon background [Units/volume] in Blood by Immunoassay

Term Description

This represents the baseline value for interferon-gamma release assays (IGRA). Elevated levels of IFN-gamma in the background ("Nil") sample may occur with the presence of heterophile antibodies, or to intrinsic IFN-gamma secretion.

Release 2.69: DefinitionDescription: Removed reference to QuantiFERON-TB assay from the description because this term is not specific for that assay.; Previous Releases: The EIA method, which was always intended to cover more than just enzyme-linked immunoassay and whose display name for the long common name has always been Immunoassay, was renamed IA in order to eliminate ambiguity about whether the method has a broader meaning than just enzyme-linked immunoassay. Likewise, EIA.rapid was renamed IA.rapid. These changes were approved by the Laboratory LOINC Committee in June 2016.

71772-8 Mitogen stimulated gamma interferon [Units/volume] in Blood

Term 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.

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.

Term Description

The quantitative levels (uncorrected for background) for an IFN-gamma response by CD4+ T-helper and CD8+ T cytotoxic lymphocytes stimulated by the presence of TB antigens, specifically ESAT-6 and CFP-10. This term was created for, but not limited in use to, the QuantiFERON-TB Gold Plus test, which includes two tubes with the Mycobacterium tuberculosis (MTB)-complex-associated antigens ESAT-6 and CFP-10 that stimulate a cell-mediated immunity (CMI) response. The first tube contains antigens that stimulate a response from CD4+ T-helper lymphocytes [LOINC: 64084-7], and the second tube (this term) contains the antigens included in tube 1 as well as an additional set of peptides targeting the CMI response from CD8+ cytotoxic T lymphocytes. In the QuantiFERON-TB Gold Plus test, the amount of IFN-gamma is 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.

Part Descriptions

LP149676-1   Mycobacterium tuberculosis stimulated gamma interferon
Interferon-γ (interferon-gamma) release assays (IGRAs) are based on the ability of the Mycobacterium tuberculosis antigens for early secretory antigen target 6 (ESAT-6) and culture filtrate protein 10 (CFP-10) to stimulate host production of interferon-gamma. Because these antigens are not present in non-tuberculous mycobacteria or in any BCG vaccine variant, these tests can distinguish latent tuberculosis infection (LTBI). The blood tests QuantiFERON-TB Gold In-Tube and T-SPOT.TB use these antigens to detect people with tuberculosis. Lymphocytes from the patient's blood are incubated with the antigens. If the patient has been exposed to tuberculosis before, T lymphocytes produce interferon γ in response. These tests are both interferon γ tests but they are not equivalent. The QuantiFERON-TB Gold In-Tube uses an ELISA format to quantify the total amount of interferon γ when whole blood is exposed to the antigens (ESAT-6,CFP-10 and TB 7.7). T-SPOT.TB is a type of enzyme-linked immunospot assay (ELISPOT) assay, which counts the number of activated T lymphocytes that secrete interferon γ.

Change Reason
The PrThr property is used for LOINC terms whose results are reported using an ordered categorical scale, regardless of whether or not an internal threshold was used to make that determination. This change was approved by the Laboratory LOINC Committee in June 2016.; Updated Property from 'PrThr' to 'Imp' since the result for this observation is the overall interpretation of the assay.
