Order TB Gold Blood Test | QuantiFERON Tuberculosis Lab TestThe QuantiFERON-TB Gold test is a blood-based method for detecting infection with Mycobacterium tuberculosis, the bacterium that causes tuberculosis. Unlike traditional skin testing, this assay measures the body's immune response directly from a blood sample, offering a laboratory perspective on TB exposure and infection status.
About TB Gold Blood Test | QuantiFERON Tuberculosis Lab Test in Altadena
QuantiFERON-TB Gold is an interferon-gamma release assay (IGRA) used to identify individuals who have been infected with tuberculosis bacteria.
The test works by mixing a patient's white blood cells with specific M. tuberculosis antigens. If the person has been exposed to TB, their immune cells release interferon-gamma, which the assay detects and quantifies.
This approach differs from the tuberculin skin test, which requires a follow-up visit to read the result and can be influenced by prior BCG vaccination. The QuantiFERON-TB Gold blood test avoids those variables by measuring a direct immune response in a single sample.
Results are typically reported as positive, negative, or indeterminate. An indeterminate result may occur if the immune cells do not respond adequately in the collection tube, and repeat testing may be considered in such cases.
