About TB Gold Blood Test | QuantiFERON Tuberculosis Lab Test in Newark
The QuantiFERON-TB Gold test is an interferon-gamma release assay (IGRA) used to identify prior exposure to tuberculosis bacteria.
The test measures the amount of interferon-gamma released by a person's white blood cells when they are mixed with specific antigens from Mycobacterium tuberculosis. A positive result indicates that the immune system has been sensitized to these bacteria at some point.
Because the test uses a blood sample, it is not affected by prior BCG vaccination, which can cause false-positive results on the traditional tuberculin skin test. It also eliminates the need for a second visit to have a skin reaction measured.
QuantiFERON-TB Gold cannot distinguish between latent tuberculosis infection and active tuberculosis disease. A positive result requires further evaluation by a healthcare provider, often including a chest radiograph and additional clinical assessment, to determine whether the infection is latent or active.
