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 the bacteria that cause tuberculosis. Unlike the traditional tuberculin skin test, this assay uses a blood sample and measures the immune system's response to specific TB antigens, offering a clearer picture of whether a person has been exposed to the pathogen.
About TB Gold Blood Test | QuantiFERON Tuberculosis Lab Test in Severna Park
QuantiFERON-TB Gold is an interferon-gamma release assay, or IGRA, designed to identify latent or active tuberculosis infection.
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 release interferon-gamma in response, which the assay quantifies.
Because the antigens used are absent from most non-tuberculous mycobacteria and from the BCG vaccine, the QuantiFERON test is less likely than a skin test to produce a false positive result in people who have received BCG vaccination.
Results are reported as positive, negative, or indeterminate. A positive result indicates that TB infection is likely and should be evaluated further by a healthcare provider, while a negative result suggests no infection was detected. An indeterminate result means the test could not provide a reliable answer, often due to low immune cell activity or technical factors, and repeat testing may be considered.
