Order TB Gold Blood Test | QuantiFERON Tuberculosis Lab TestThe QuantiFERON-TB Gold test is a blood assay used to detect infection with Mycobacterium tuberculosis, the bacterium that causes tuberculosis. Unlike skin testing, it relies on an immune response measured in a blood sample, which allows for a controlled laboratory assessment without the need for a follow-up visit to read a skin reaction.
About TB Gold Blood Test | QuantiFERON Tuberculosis Lab Test in San Antonio
This test is designed to identify evidence of TB infection by measuring the release of interferon-gamma from white blood cells when they are exposed to specific TB antigens.
The assay uses a blood sample collected into specialized tubes containing antigens that stimulate lymphocytes previously sensitized to M. tuberculosis. If the person has been infected, their cells release interferon-gamma, which is then quantified.
QuantiFERON-TB Gold is one of several interferon-gamma release assays (IGRAs) used in clinical practice. It does not distinguish between latent TB infection and active TB disease; additional evaluation is required if the result is positive.
Because the test measures an immune response rather than direct bacterial presence, it can be affected by conditions that alter immune function. Results are interpreted alongside clinical history, symptoms, and other diagnostic findings.
