Order TB Gold Blood Test | QuantiFERON Tuberculosis Lab TestThe TB Gold Blood Test, also known as the QuantiFERON Tuberculosis Lab Test, is a blood-based method for detecting infection with Mycobacterium tuberculosis, the bacterium that causes tuberculosis. Unlike traditional skin testing, this assay measures the immune system's response to specific TB antigens directly in a blood sample, offering a laboratory-based approach to TB screening.
About TB Gold Blood Test | QuantiFERON Tuberculosis Lab Test in Tempe
The QuantiFERON TB Gold test is an interferon-gamma release assay (IGRA) that evaluates cell-mediated immunity to TB-specific antigens.
The test works by incubating a blood sample with synthetic peptides that mimic proteins found in Mycobacterium tuberculosis. If the person has been infected with TB, their T cells will recognize these peptides and release interferon-gamma, a cytokine that can be measured in the laboratory.
The QuantiFERON TB Gold assay includes a nil control to measure background interferon-gamma production and a mitogen control to verify that the immune cells are functioning properly. Results are interpreted by comparing the interferon-gamma response to the TB antigens against these controls, yielding a qualitative result of positive, negative, or indeterminate.
This test does not distinguish between latent TB infection and active tuberculosis disease. A positive result indicates that the person has been infected with TB bacteria at some point, but further clinical evaluation is needed to determine whether the infection is latent or active.
