Order TB Gold Blood Test | QuantiFERON Tuberculosis Lab TestTuberculosis remains one of the world's most persistent infectious diseases, and detecting latent infection before it becomes active disease is a central part of public health strategy. The TB Gold blood test, known clinically as QuantiFERON, offers a blood-based method for identifying whether a person's immune system has been exposed to the bacteria that cause TB.
About TB Gold Blood Test | QuantiFERON Tuberculosis Lab Test in Orange
The QuantiFERON TB Gold test measures the immune system's response to specific proteins produced by Mycobacterium tuberculosis.
When someone has been exposed to the tuberculosis bacterium, certain white blood cells become sensitized to its antigens. The test works by mixing a blood sample with these antigens and measuring the amount of interferon-gamma the cells release in response. A measurable reaction indicates that the immune system has encountered TB bacteria at some point.
Unlike the traditional tuberculin skin test, which requires a follow-up visit to read the result, the TB Gold test needs only a single blood draw. This removes the subjectivity of interpreting a skin reaction and eliminates the need for a second appointment. It also avoids false readings that can occur in people who have received the BCG vaccine, since the test targets antigens not found in that vaccine.
Results are typically classified as positive, negative, or indeterminate. A positive result shows that TB infection is likely present, though it does not by itself distinguish between latent infection and active disease. An indeterminate result means the test could not produce a clear answer, often because of a low white blood cell count or a problem with the sample, and repeat testing may be considered. Interpretation always belongs with a qualified healthcare provider who can weigh the result against symptoms, history, and other findings.
