About TB Gold Blood Test | QuantiFERON Tuberculosis Lab Test in Mclean
This laboratory test is a form of interferon-gamma release assay (IGRA) used to identify prior exposure to tuberculosis.
The test works by mixing a blood specimen with peptides that mimic proteins found in Mycobacterium tuberculosis. If the immune system has been previously exposed to the bacterium, T cells in the sample release interferon-gamma, which the assay quantifies.
A positive result indicates that the immune system has responded to TB antigens at some point. It does not distinguish between latent TB infection and active tuberculosis disease, so clinical evaluation and additional testing are necessary to determine the appropriate next steps.
The QuantiFERON TB Gold test requires a blood draw, typically from a vein in the arm. Results are usually available within one to three business days, and no special preparation is generally needed beyond following the laboratory's instructions.
