Order TB Gold Blood Test | QuantiFERON Tuberculosis Lab TestThe TB Gold Blood Test, also known as the QuantiFERON tuberculosis lab test, is a blood-based method for detecting infection with the bacterium that causes tuberculosis. It offers a laboratory alternative to traditional skin testing and is used to identify whether a person has been exposed to the TB organism.
About TB Gold Blood Test | QuantiFERON Tuberculosis Lab Test in Norwalk
Tuberculosis is an infectious disease caused by Mycobacterium tuberculosis, a bacterium that typically affects the lungs and can spread from person to person through the air.
The QuantiFERON TB Gold test works by measuring the immune system's response to specific proteins associated with the TB bacterium. A blood sample is collected and exposed to these antigens in the laboratory, and the resulting reaction is quantified to indicate whether infection is likely present.
This test does not distinguish between latent TB infection and active TB disease. A positive result means the immune system has recognized TB antigens, but additional clinical evaluation and other tests are needed to determine whether the infection is dormant or active.
Because it requires only a single blood draw and does not involve skin pricks or multiple visits, the TB Gold blood test is often preferred for individuals who have received the BCG vaccine or who may have difficulty returning for a second appointment. Results are typically available within one to three business days.
