Order TB Gold Blood Test | QuantiFERON Tuberculosis Lab TestThe QuantiFERON-TB Gold test is a blood-based method for detecting infection with Mycobacterium tuberculosis, the bacterium that causes tuberculosis. Unlike traditional skin testing, it relies on the immune response of white blood cells in a collected sample, offering a laboratory-based approach to TB screening.
About TB Gold Blood Test | QuantiFERON Tuberculosis Lab Test in Gloucester
QuantiFERON-TB Gold measures how a patient's immune cells react to specific tuberculosis proteins.
The test works by incubating a blood sample with synthetic peptides that mimic proteins found in Mycobacterium tuberculosis. If the patient's immune cells have been previously exposed to TB, they release interferon-gamma, which the assay detects and quantifies.
This method distinguishes tuberculosis infection from most nontuberculous mycobacteria and from prior BCG vaccination, which can cause false-positive results on traditional tuberculin skin tests. The test requires a single blood draw and does not involve injecting any substance into the skin.
Results are reported as positive, negative, or indeterminate. An indeterminate result may occur if the immune cells in the sample do not respond adequately to the test controls, and a repeat sample may be requested in such cases. The test does not distinguish between latent TB infection and active TB disease; additional clinical evaluation is needed if the result is positive.
