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, it relies on the immune response measured in a blood sample rather than a skin reaction.
About TB Gold Blood Test | QuantiFERON Tuberculosis Lab Test in Norwalk
The QuantiFERON TB Gold test is designed to identify whether a person has been infected with Mycobacterium tuberculosis, the organism responsible for tuberculosis.
Tuberculosis is an infectious disease that spreads from person to person through the air and most commonly affects the lungs, though it can involve other parts of the body. Many people who carry the bacterium do not feel ill and are not contagious, a state known as latent tuberculosis infection.
The QuantiFERON test works by mixing a blood sample with specific antigens derived from the tuberculosis bacterium. If the person's immune cells have encountered the bacterium before, they release a detectable signal called interferon-gamma. The laboratory measures this response to determine whether infection is likely.
Because the test uses a blood draw, it requires only a single visit for sample collection. Results are typically available within one to three business days, and preparation follows the laboratory's instructions. A positive result indicates probable infection and generally prompts further evaluation by a healthcare provider.
