Order TB Gold Blood Test | QuantiFERON Tuberculosis Lab TestThe TB Gold Blood Test, also known as the QuantiFERON-TB Gold test, is a blood-based method for detecting infection with Mycobacterium tuberculosis, the bacterium that causes tuberculosis. Unlike the traditional tuberculin skin test, this assay measures the immune system's response to specific TB antigens directly in a blood sample, offering a laboratory-based approach to TB screening.
About TB Gold Blood Test | QuantiFERON Tuberculosis Lab Test in Kent
The QuantiFERON-TB Gold test is an interferon-gamma release assay (IGRA) that aids in identifying individuals who have been infected with tuberculosis bacteria.
The test works by mixing a blood sample with synthetic peptides that mimic proteins found in Mycobacterium tuberculosis. If the person's immune cells have previously encountered TB bacteria, they will release interferon-gamma in response to these peptides. The amount of interferon-gamma produced is measured and compared against negative and positive controls to determine the result.
Because the antigens used in the QuantiFERON-TB Gold test are specific to Mycobacterium tuberculosis and are not shared with the BCG vaccine or most non-tuberculous mycobacteria, the test can distinguish TB infection from prior BCG vaccination. This makes it a useful tool in settings where BCG vaccination is common.
The test requires a blood draw, typically collected in specialized tubes provided by the laboratory. Results are generally available within a few business days. A positive result indicates likely infection with TB bacteria, while a negative result suggests no infection, though factors such as immune suppression can affect the outcome. The test does not distinguish between latent TB infection and active TB disease, so clinical evaluation is necessary for proper interpretation.
