About TB Gold Blood Test | QuantiFERON Tuberculosis Lab Test in Short Pump
The QuantiFERON-TB Gold test is an interferon-gamma release assay, or IGRA, used to identify prior exposure to the tuberculosis bacterium.
When a person has been infected with Mycobacterium tuberculosis, certain white blood cells release interferon-gamma after being exposed to specific proteins from the bacterium. The QuantiFERON-TB Gold test measures that release in a blood sample, which is why it is classified as an interferon-gamma release assay.
The test uses a set of antigens that are absent from the BCG vaccine and from most non-tuberculous mycobacteria. This design reduces false-positive results that can occur with the tuberculin skin test in people who have received the BCG vaccine. Results are reported as positive, negative, or indeterminate.
A positive result indicates that the immune system has responded to tuberculosis antigens, but it does not by itself distinguish between latent tuberculosis infection and active tuberculosis disease. An indeterminate result means the test could not produce a clear answer, often because of a low lymphocyte count or a problem with the sample, and repeat testing may be considered.
