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 the traditional tuberculin skin test, this assay uses a blood sample and measures the immune system's response to specific TB antigens. It is a tool for identifying latent or active TB infection, though it does not distinguish between the two on its own.
About TB Gold Blood Test | QuantiFERON Tuberculosis Lab Test in Berkeley
The QuantiFERON-TB Gold test is an interferon-gamma release assay (IGRA) that offers a blood-based alternative to skin testing for tuberculosis infection.
The test works by mixing a patient's blood with synthetic peptides that mimic proteins found in M. tuberculosis. If the person has been infected, their T cells will recognize these peptides and release interferon-gamma, a cytokine that can be measured in the laboratory.
Because the antigens used are specific to M. tuberculosis and absent from the BCG vaccine and most non-tuberculous mycobacteria, the QuantiFERON-TB Gold test is less likely than the skin test to produce false-positive results in individuals who have received the BCG vaccine.
Results are typically reported as positive, negative, or indeterminate. A positive result indicates that the immune system has been exposed to TB bacteria, but it does not by itself confirm active disease; further clinical evaluation is required to determine whether the infection is latent or active.
