The TB Gold blood test, also known as the QuantiFERON-TB Gold test, is a laboratory method for detecting infection with the bacterium that causes tuberculosis. Unlike traditional skin testing, this assay uses a blood sample to measure the immune system's response to specific TB antigens, offering a clearer picture of whether a person has been exposed to the pathogen.

About TB Gold Blood Test | QuantiFERON Tuberculosis Lab Test in Logan

Understanding how the QuantiFERON-TB Gold test works helps put its results in context.

The test measures the release of interferon-gamma by white blood cells when they are mixed with synthetic peptides that mimic proteins found in Mycobacterium tuberculosis. If the immune system has encountered TB before, those cells will produce a measurable amount of interferon-gamma, which the assay detects and quantifies.

Because the antigens used are specific to M. tuberculosis and absent from the BCG vaccine and most non-tuberculous mycobacteria, the QuantiFERON-TB Gold test is less likely than a skin test to produce a false positive result in people who have received the BCG vaccine. It also requires only a single blood draw and a follow-up laboratory analysis, avoiding the need for a second visit to have a skin reaction read.

Results are typically reported as positive, negative, or indeterminate. A positive result indicates that the immune system has likely been exposed to TB bacteria at some point, but it does not by itself distinguish between latent infection and active disease. A negative result makes infection less likely, though it may occur in some individuals with weakened immune systems. An indeterminate result means the test could not provide a clear answer, often because of a problem with the sample or the patient's immune response, and repeat testing may be considered.
