Order TB Gold Blood Test | QuantiFERON Tuberculosis Lab TestThe TB Gold Blood Test, commonly known as the QuantiFERON Tuberculosis Lab Test, is a blood-based method for detecting infection with Mycobacterium tuberculosis, the bacterium that causes tuberculosis. Unlike skin tests that require a follow-up visit for interpretation, this assay measures the immune system's response directly in a blood sample.
About TB Gold Blood Test | QuantiFERON Tuberculosis Lab Test in Drexel Heights
The QuantiFERON TB Gold test is an interferon-gamma release assay, or IGRA, designed to identify prior exposure to tuberculosis bacteria.
The test works by mixing a blood sample with specific antigens derived from Mycobacterium tuberculosis. If the person's immune cells have encountered TB before, they release interferon-gamma, a signaling protein that the test detects and quantifies.
A positive result indicates that the immune system has been sensitized to TB bacteria at some point, but it does not distinguish between latent infection and active disease. Additional clinical evaluation and imaging are typically needed to make that distinction.
Because the assay uses a blood draw rather than a skin prick, it avoids the need for a return visit and is not affected by prior BCG vaccination, which can cause false-positive results on traditional skin tests.
