Order TB Gold Blood Test | QuantiFERON Tuberculosis Lab TestThe QuantiFERON-TB Gold test is a blood assay used to detect an immune response to Mycobacterium tuberculosis, the bacterium that causes tuberculosis. Unlike skin testing, it relies on a single blood draw and measures the release of interferon-gamma by sensitized white blood cells.
About TB Gold Blood Test | QuantiFERON Tuberculosis Lab Test in Central
Tuberculosis remains a significant infectious disease worldwide, and accurate detection of latent infection is central to public health efforts.
The QuantiFERON-TB Gold test works by incubating a patient's blood with synthetic peptides that represent antigens specific to M. tuberculosis. If the person's immune system has been previously exposed to the bacterium, their T cells will release interferon-gamma in response.
This method distinguishes itself from the tuberculin skin test in several ways. It requires only one visit for a blood sample, avoids subjective interpretation of skin induration, and is not affected by prior BCG vaccination, which can cause false-positive skin test results.
Results are typically reported as positive, negative, or indeterminate, with quantitative values for the interferon-gamma response. A positive result indicates likely infection with M. tuberculosis, but it does not differentiate between latent infection and active disease; additional clinical evaluation is necessary.
