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, also known as the QuantiFERON tuberculosis lab test, offers a blood-based method for identifying whether a person has been infected with the bacteria that cause TB.
About TB Gold Blood Test | QuantiFERON Tuberculosis Lab Test in Normal
The QuantiFERON TB Gold test is an interferon-gamma release assay, or IGRA, that measures the immune system's response to specific tuberculosis antigens.
Unlike the traditional tuberculin skin test, which requires a follow-up visit to read the reaction, this blood test is performed on a single blood sample drawn at the laboratory. The sample is exposed to synthetic peptides that mimic proteins found in Mycobacterium tuberculosis, and the amount of interferon-gamma released by white blood cells is measured.
A positive result indicates that the immune system has been exposed to TB bacteria at some point. It does not by itself distinguish between latent TB infection, in which the bacteria are present but inactive and not contagious, and active TB disease, which causes symptoms and can be transmitted to others. Additional evaluation is needed to make that distinction.
The test is generally not affected by prior BCG vaccination, which can cause false-positive results on the skin test, and it does not require a return visit for interpretation. Results are typically available within a few business days, and preparation instructions should be followed as provided by the laboratory performing the collection.
