Part Description

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.
