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 testing, it requires a single blood draw and does not depend on a follow-up visit to read a reaction.
About TB Gold Blood Test | QuantiFERON Tuberculosis Lab Test in Roswell
Tuberculosis is an infectious disease caused by Mycobacterium tuberculosis, a bacterium transmitted through the air when a person with active respiratory disease coughs, speaks, or sings.
The QuantiFERON assay works by measuring the immune response of white blood cells to specific antigens derived from M. tuberculosis. A blood sample is mixed with these antigens, and the amount of interferon-gamma released is quantified. This laboratory signal indicates whether the immune system has previously encountered the bacterium.
Because the test uses antigens absent from most nontuberculous mycobacteria and from the BCG vaccine, it can distinguish true M. tuberculosis exposure from prior BCG vaccination more reliably than traditional skin testing. It also avoids the subjectivity of measuring a skin induration and the need for a return visit within a narrow reading window.
A positive result indicates infection with M. tuberculosis, but it does not by itself distinguish latent infection from active disease. Diagnostic interpretation therefore combines the laboratory result with clinical evaluation, imaging, and other microbiologic studies as appropriate.
