Order TB Gold Blood Test | QuantiFERON Tuberculosis Lab TestThe TB Gold Blood Test, also known as the QuantiFERON-TB Gold test, is a laboratory method for detecting infection with Mycobacterium tuberculosis, the bacterium that causes tuberculosis. Unlike traditional skin testing, this assay uses a blood sample to measure the immune system's response to specific TB proteins, offering a clearer picture of whether a person has been exposed to the bacterium.
About TB Gold Blood Test | QuantiFERON Tuberculosis Lab Test in Berkeley
The QuantiFERON-TB Gold test is an interferon-gamma release assay, or IGRA, designed to identify latent or active tuberculosis infection through a blood draw rather than a skin prick.
The test works by mixing a patient's blood with synthetic peptides that mimic proteins found in Mycobacterium tuberculosis. If the person's immune cells have previously encountered TB, they release interferon-gamma, a signaling molecule that the lab measures. A positive result indicates that the immune system has been sensitized to TB, though it cannot by itself distinguish between latent infection and active disease.
QuantiFERON-TB Gold requires only a single blood collection, typically into specialized tubes, and does not require a follow-up visit for interpretation as skin tests do. Because the assay uses antigens absent from most nontuberculous mycobacteria and from the BCG vaccine, it tends to produce fewer false-positive results in people who have received BCG vaccination.
Results are generally available within a few business days. A negative result suggests no detectable immune response to TB, while a positive result warrants further clinical evaluation, which may include chest imaging, sputum analysis, and a medical history review. Indeterminate results can occur if the immune response is too low or too high to interpret, and repeat testing may be advised in such cases.
