Order TB Gold Blood Test | QuantiFERON Tuberculosis Lab TestThe TB Gold blood test, commonly known as QuantiFERON, is a laboratory method for detecting infection with the bacterium that causes tuberculosis. Unlike traditional skin testing, it relies on a blood sample and measures the immune system's response to specific TB antigens. This makes it a useful tool in screening and diagnostic workflows, particularly when a clear distinction between latent and active infection is needed.
About TB Gold Blood Test | QuantiFERON Tuberculosis Lab Test in Memphis
QuantiFERON is an interferon-gamma release assay, or IGRA, designed to identify evidence of TB infection without the variables that can complicate skin testing.
The test works by mixing a blood sample with antigens derived from Mycobacterium tuberculosis. If the person's immune cells have prior exposure to TB, they release interferon-gamma, which the assay detects and quantifies. A negative result suggests no detectable immune response to those antigens, while a positive result indicates likely infection with TB bacteria.
Because QuantiFERON uses a blood draw, it avoids the need for a follow-up visit to read a skin test and is not affected by prior BCG vaccination, which can cause false-positive skin test results. It also reduces the influence of reader variability that can occur with skin testing. However, like any diagnostic tool, results must be interpreted alongside clinical history, symptoms, and other findings.
The test does not distinguish between latent TB infection and active tuberculosis disease. A positive result means the immune system has recognized TB antigens, but additional evaluation is required to determine whether the infection is latent or active. Turnaround time is typically one to three business days, and preparation follows the laboratory's instructions.
