Order TB Gold Blood Test | QuantiFERON Tuberculosis Lab TestThe TB Gold Blood Test, also known as the QuantiFERON Tuberculosis Lab Test, is a blood-based method for detecting infection with the bacterium that causes tuberculosis. Unlike skin tests that require a follow-up reading, this assay uses a single blood draw and laboratory analysis to measure the body's immune response to specific TB antigens.
About TB Gold Blood Test | QuantiFERON Tuberculosis Lab Test in Bothell
The QuantiFERON TB Gold test is an interferon-gamma release assay (IGRA) that identifies whether a person has been infected with Mycobacterium tuberculosis.
The test works by mixing a blood sample with synthetic peptides that mimic proteins found in M. tuberculosis. If the person's immune cells have prior exposure to these proteins, they release interferon-gamma, a cytokine that can be measured in the laboratory.
Results are typically reported as positive, negative, or indeterminate. A positive result suggests infection with TB bacteria, but it does not distinguish between latent TB infection and active TB disease. Additional clinical evaluation and diagnostic testing are needed to make that distinction.
The QuantiFERON TB Gold test is not affected by prior BCG vaccination, which is a common cause of false-positive results on traditional tuberculin skin tests. It also requires only one visit for blood collection, with no need for a return visit to have the test read.
