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 bacteria that cause tuberculosis. Unlike skin testing, it relies on a single blood draw and laboratory analysis of the immune response, which can make it a practical option for many patients and clinical settings.
About TB Gold Blood Test | QuantiFERON Tuberculosis Lab Test in Suisun City
The QuantiFERON TB Gold test is an interferon-gamma release assay, often abbreviated as IGRA. It measures how a person's white blood cells react when exposed to specific proteins from Mycobacterium tuberculosis in a laboratory culture.
When a person has been infected with tuberculosis bacteria, certain immune cells in the blood become sensitized to those organisms. In the QuantiFERON test, a sample of blood is mixed with small pieces of TB proteins and incubated. If the cells recognize the proteins, they release interferon-gamma, a signaling molecule that the test detects and quantifies.
The test is designed to identify infection with the tuberculosis bacterium, including latent tuberculosis infection, in which a person carries the organism without feeling ill and is not contagious. It does not distinguish latent infection from active tuberculosis disease. A diagnosis of active TB requires additional evaluation, such as imaging, sputum studies, and clinical assessment by a healthcare provider.
Because the QuantiFERON assay uses a blood sample rather than a skin prick, it avoids some of the variables that can complicate tuberculin skin testing, such as prior BCG vaccination and reader interpretation. Results are reported as positive, negative, or indeterminate, and an indeterminate result may occur when the immune response in the sample is not strong enough to interpret reliably.
