Description

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.
