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. Unlike skin tests that require a follow-up visit for interpretation, this assay measures the immune response directly in a blood sample, offering a clearer picture of whether someone has been exposed to the TB organism.
About TB Gold Blood Test | QuantiFERON Tuberculosis Lab Test in Franklin
The QuantiFERON TB Gold test is an interferon-gamma release assay, or IGRA, designed to identify latent or active tuberculosis infection.
The test works by mixing a blood sample with specific antigens derived from Mycobacterium tuberculosis. If the person's immune cells have prior experience with the TB bacterium, they release interferon-gamma, a signaling protein that the lab can measure.
This approach avoids cross-reactivity with the BCG vaccine, which is commonly given in countries with high TB rates, and it does not require the multiple visits associated with traditional tuberculin skin testing. Results are typically reported within a few business days.
TB Gold is used in screening programs, contact investigations, and clinical evaluations where tuberculosis is suspected. It does not distinguish between latent infection and active disease, so healthcare providers interpret the result alongside symptoms, imaging, and other laboratory findings.
