Order TB Gold Blood Test | QuantiFERON Tuberculosis Lab TestThe TB Gold Blood Test, also known as the QuantiFERON Tuberculosis Lab Test, is a blood-based method for detecting infection with the bacterium that causes tuberculosis. Unlike traditional skin testing, this assay measures the immune system's response in a blood sample, offering a laboratory-based approach to TB screening.
About TB Gold Blood Test | QuantiFERON Tuberculosis Lab Test in Downey
The QuantiFERON TB Gold test assesses whether a person has been infected with Mycobacterium tuberculosis by measuring interferon-gamma released by white blood cells in response to specific TB antigens.
The test works by incubating a blood sample with peptides that mimic proteins found in Mycobacterium tuberculosis. If the person's immune cells have prior exposure to TB, they release interferon-gamma, which is then quantified. This design helps distinguish TB infection from most nontuberculous mycobacteria and from prior BCG vaccination, which can complicate skin test interpretation.
QuantiFERON TB Gold is typically used as a screening tool for individuals who may have been exposed to TB or who are at increased risk due to occupational or medical factors. It requires a single blood draw, and results are generally reported qualitatively as positive, negative, or indeterminate. An indeterminate result may occur if the immune response is insufficient or if the sample handling is suboptimal, and repeat testing may be considered.
This test does not differentiate between latent TB infection and active TB disease. A positive result indicates that the immune system has been sensitized to TB antigens, but further clinical evaluation, including imaging and microbiologic testing, is needed to determine whether the infection is latent or active. The test is not a substitute for a medical examination, and results should be interpreted in the context of the individual's history and risk factors.
