Order TB Gold Blood Test | QuantiFERON Tuberculosis Lab TestTuberculosis remains one of the most consequential infectious diseases worldwide, and detecting latent infection before it progresses to active disease is a central public-health strategy. The QuantiFERON TB Gold blood test offers a laboratory-based method for identifying immune sensitization to Mycobacterium tuberculosis without relying on a skin prick.
About TB Gold Blood Test | QuantiFERON Tuberculosis Lab Test in Altadena
The QuantiFERON TB Gold test is an interferon-gamma release assay, commonly abbreviated as IGRA.
White blood cells from a collected specimen are exposed in the laboratory to specific antigens derived from Mycobacterium tuberculosis. If the immune system has previously encountered the bacterium, those cells release interferon-gamma, which the assay measures.
Because the test uses a blood draw rather than a skin test, it requires only a single visit to the laboratory for specimen collection. Results are typically reported within one to three business days, though the exact interval depends on the performing laboratory.
The assay distinguishes immune sensitization from active disease. A reactive result indicates that the immune system has responded to tuberculosis antigens at some point, but it does not by itself confirm active tuberculosis. Clinical evaluation and additional testing are needed to interpret any result in context.
