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 the bacterium that causes tuberculosis. It offers a laboratory alternative to traditional skin testing and is used to evaluate whether a person has been exposed to the TB organism.
About TB Gold Blood Test | QuantiFERON Tuberculosis Lab Test in Merced
Tuberculosis is an infectious disease caused by Mycobacterium tuberculosis, a bacterium transmitted through the air when a person with active respiratory TB coughs, speaks, or sings.
The QuantiFERON TB Gold test works by measuring the immune response of white blood cells to specific antigens derived from M. tuberculosis. A blood sample is mixed with these antigens, and if the cells have been previously sensitized to the bacterium, they release interferon-gamma, which the laboratory detects and quantifies.
This test distinguishes itself from the tuberculin skin test in several ways. It requires only a single blood draw rather than a two-visit skin procedure, and because it uses antigens that are more specific to M. tuberculosis, it is less likely to produce false-positive results in people who have received the BCG vaccine or who are infected with most nontuberculous mycobacteria.
TB infection exists on a spectrum. Latent tuberculosis infection means the bacterium is present in the body but kept in check by the immune system, causing no symptoms and no contagiousness. Active TB disease occurs when the bacterium multiplies and causes illness, most often in the lungs. The QuantiFERON test helps identify whether infection has occurred, but it cannot by itself distinguish latent from active disease, so clinical evaluation and additional testing may be needed.
