About TB Gold Blood Test | QuantiFERON Tuberculosis Lab Test in Williamsburg
The QuantiFERON TB Gold test evaluates whether a person's immune cells have been exposed to Mycobacterium tuberculosis, the organism responsible for tuberculosis.
The test works by mixing a blood sample with specific TB antigens and measuring the amount of interferon-gamma released by sensitized white blood cells. A positive result indicates likely infection with M. tuberculosis, while a negative result suggests no immune response was detected.
Tuberculosis is an infectious disease that spreads through the air when a person with active respiratory TB coughs or sneezes. Many people who carry the bacterium have latent TB infection, meaning they are not sick and cannot transmit the disease, but they may develop active TB later without treatment.
The QuantiFERON test is one of several tools used to screen for TB infection. It does not distinguish between latent and active tuberculosis, so clinical evaluation and additional testing are needed when results are positive. Turnaround time for results is typically one to three business days.
