Quick answer
The TB Gold blood test, commonly known as QuantiFERON, checks whether a person has been infected with the bacteria that cause tuberculosis. It works by measuring the immune system's response to specific TB proteins in a blood sample. Unlike a skin test, it needs only one visit and no second reading. Results help clinicians evaluate latent or active TB infection.
What this test measures
Tuberculosis is caused by Mycobacterium tuberculosis, a bacterium that usually affects the lungs and can remain inactive for years. The QuantiFERON assay measures interferon-gamma released by white blood cells when they encounter TB-specific antigens. This immune response indicates prior exposure to the bacterium. Clinicians use the result alongside symptoms, imaging, and other tests when evaluating possible latent or active infection.
The sample is whole blood collected into specialized tubes that contain TB antigens, a negative control, and a positive control. After incubation, the laboratory measures interferon-gamma in the plasma. The assay targets antigens such as ESAT-6 and CFP-10, which are absent from most BCG vaccine strains and from many non-tuberculous mycobacteria, which improves specificity compared with older skin testing.
The test is often requested for people who have had close contact with someone with active TB, for healthcare and congregate-setting workers, for people starting certain biologic treatments, and for those born or living in regions where TB is more common. It is a screening tool and does not by itself confirm active disease, so a qualified healthcare provider interprets it with the full clinical picture.
