Order TB Gold Blood Test | QuantiFERON Tuberculosis Lab TestTuberculosis remains one of the world's most persistent infectious diseases, and detecting it accurately is central to controlling its spread. The QuantiFERON TB Gold blood test offers a laboratory method for identifying an immune response to the bacteria that cause TB, using a single blood draw rather than a skin test.
About TB Gold Blood Test | QuantiFERON Tuberculosis Lab Test in Lancaster
The QuantiFERON TB Gold test is an interferon-gamma release assay (IGRA) that measures how a person's immune cells respond to specific proteins associated with Mycobacterium tuberculosis.
The test works by mixing a blood sample with antigens that are unique to the tuberculosis bacteria. If the person's immune system has been exposed to TB, certain white blood cells will release interferon-gamma, which the laboratory can detect and measure.
Because the assay relies on a blood sample, it avoids the need for a follow-up visit to read a skin test result. It also distinguishes TB infection from most nontuberculous mycobacteria and from the BCG vaccine, which can cause false-positive skin test reactions.
Results are typically available within one to three business days. A positive result indicates likely TB infection and generally prompts further evaluation, while a negative result makes active infection less likely but does not rule it out in every clinical situation.
