Order TB Gold Blood Test | QuantiFERON Tuberculosis Lab TestTuberculosis remains one of the most consequential infectious diseases worldwide, and identifying latent infection before it progresses to active disease is a central goal of public health screening. The QuantiFERON-TB Gold test offers a blood-based method for detecting immune sensitization to Mycobacterium tuberculosis, the bacterium that causes TB.
About TB Gold Blood Test | QuantiFERON Tuberculosis Lab Test in Upland
The QuantiFERON-TB Gold test is an interferon-gamma release assay, commonly abbreviated as IGRA.
Unlike the traditional tuberculin skin test, which requires a follow-up visit to measure a skin reaction, the QuantiFERON-TB Gold test is performed on a single blood sample. The sample is stimulated with specific M. tuberculosis antigens, and the amount of interferon-gamma released by sensitized T cells is measured. This approach helps distinguish true infection with M. tuberculosis from responses caused by most nontuberculous mycobacteria and from prior BCG vaccination.
The test is used to detect infection with M. tuberculosis, including latent tuberculosis infection, in which a person carries the bacterium without symptoms and is not contagious. It does not by itself distinguish latent from active tuberculosis disease. When active disease is suspected, additional evaluation such as imaging, sputum studies, and clinical assessment is required.
Results are typically reported as positive, negative, or indeterminate. An indeterminate result can occur when the immune response in the sample is insufficient for interpretation, and repeat testing may be considered. Because the test relies on a functional immune response, conditions or medications that suppress immunity can affect results. Interpretation should always be made by a qualified healthcare professional in the context of the individual's history, risk factors, and other findings.
